SVN rev 186139 on 2008-12-15 21:39:31Z by marius - According to the corresponding Linux, NetBSD and OpenSolaris drivers, there should be a 1us delay after every write when bit-banging the MII. Also insert barriers in order to ensure the intended ordering. These changes hopefully will solve the bus wedging occasionally experienced with DM9102A since r182461. - Deobfuscate dc_mii_readreg() a bit.

SVN rev 182583 on 2008-09-01 00:46:14Z by marius MFC: r182461 For chips with a broken DC_ISR_RX_STATE which f.e. never signals stopped nor the waiting state and also no other means to check whether the receiver is idle (see also r163774), we have no choice than to call mii_tick(9) unconditionally even in the case of the DC_REDUCED_MII_POLL handling as far as the RX side is concerned. This isn't necessarily worse than checking whether RX is idle though because unlike as with TX we're racing with the hardware, which might receive packets any time while we poll the MII, anyway.

Otherwise this would result in the watchdog timer constantly being being reloaded and thus circumvent that the watchdog ever fires in the DEVICE_POLLING case.

MFC: sys/dev/dc/if_dc.c 1.185, 1.186 (partial); sys/dev/dc/if_dcreg.h 1.52 - Consistently use if_printf() only in interface methods: if_start(), if_watchdog, etc., or in functions used only in these methods. In all other functions in the driver use device_printf(). - Use __func__ instead of typing function name. - Wrap code optimized for architectures without alignment constraints in #ifdef __NO_STRICT_ALIGNMENT rather than #ifdef __i386__. This means that amd64 now also uses the optimized code. While at it, fix a nearby style(9) bug. - In dc_setcfg() suppress printing a warning when forcing the receiver and transceiver to idle state times out for chips where the status bits in question just never change (observed in detail with DM9102A) and therefore the warning would be highly likely false positive. - In dc_ifmedia_sts() add a missing DC_UNLOCK().

Big polling(4) cleanup.
o Axe poll in trap.
o Axe IFF_POLLING flag from if_flags.
o Rework revision 1.21 (Giant removal), in such a way that
poll_mtx is not dropped during call to polling handler.
This fixes problem with idle polling.
o Make registration and deregistration from polling in a
functional way, insted of next tick/interrupt.
o Obsolete kern.polling.enable. Polling is turned on/off
with ifconfig.
Detailed kern_poll.c changes:
- Remove polling handler flags, introduced in 1.21. The are not
needed now.
- Forget and do not check if_flags, if_capenable and if_drv_flags.
- Call all registered polling handlers unconditionally.
- Do not drop poll_mtx, when entering polling handlers.
- In ether_poll() NET_LOCK_GIANT prior to locking poll_mtx.
- In netisr_poll() axe the block, where polling code asks drivers
to unregister.
- In netisr_poll() and ether_poll() do polling always, if any
handlers are present.
- In ether_poll_[de]register() remove a lot of error hiding code. Assert
that arguments are correct, instead.
- In ether_poll_[de]register() use standard return values in case of
error or success.
- Introduce poll_switch() that is a sysctl handler for kern.polling.enable.
poll_switch() goes through interface list and enabled/disables polling.
A message that kern.polling.enable is deprecated is printed.
Detailed driver changes:
- On attach driver announces IFCAP_POLLING in if_capabilities, but
not in if_capenable.
- On detach driver calls ether_poll_deregister() if polling is enabled.
- In polling handler driver obtains its lock and checks IFF_DRV_RUNNING
flag. If there is no, then unlocks and returns.
- In ioctl handler driver checks for IFCAP_POLLING flag requested to
be set or cleared. Driver first calls ether_poll_[de]register(), then
obtains driver lock and [dis/en]ables interrupts.
- In interrupt handler driver checks IFCAP_POLLING flag in if_capenable.
If present, then returns.This is important to protect from spurious
interrupts.

Stop embedding struct ifnet at the top of driver softcs. Instead the struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

The DC driver asks for an alignment of PAGE_SIZE for data buffers, but also asks that each buffer be (2048 * 256) bytes long.

- Make OF_getetheraddr() honour the "local-mac-address?" system config variable. If set to "true" OF_getetheraddr() will now return the unique MAC address stored in the "local-mac-address" property of the device's OFW node if present and the host address/system default MAC address if the node doesn't doesn't have such a property. If set to "false" the host address will be returned for all devices like before this change. This brings the behaviour of device drivers for NICs with OFW support/ FCode, i.e. dc(4) for on-board DM9102A on Sun machines, gem(4) and hme(4), regarding "local-mac-address?" in line with NetBSD and Solaris. The man pages of the respective drivers will be updated separately to reflect this change. - Remove OF_getetheraddr2() which was used as a stopgap in dc(4). Its functionality is now part of OF_getetheraddr().

MFC 1.138 - Check for transmit status and free the mbuf chain when
processing the last transmit descriptor for the frame
instead of the first descriptor. This eliminates the
bug that caused the driver to report spurious collisions
and output errors that was introduced when the driver
was changed to look at the first transmit descriptor
when it was converted to use busdma (rev 1.115).

Some integrated Davicom cards in sparc64 boxes have an all zeros MAC address in the EEPROM, and we need to get it from OpenFirmware. This isn't very pretty but time is lacking to do this in a better way this near 5.2-RELEASE. This is a RELENG_5_2 candidate.

The transmit frame status is stored in the last transmit descriptor for the frame, not the first. It is probably also not safe to free the mbuf chain as soon as the OWN bit is cleared on the first descriptor since the chip may not be done copying the frame into the transmit FIFO. Revert the part of of busdma conversion (if_dc.c rev 1.115) which changed dc_txeof() to look for the status in the first descriptor and free the mbuf chain when processing the first descriptor for the frame, and revert the matching changes elsewhere in the driver. This part of the busdma change caused the driver to report spurious collisions and output errors, even when running in full-duplex mode. Reverting the mbuf chain handling slightly complicates dc_dma_map_txbuf(), since it is responsible for setting the OWN bits on the descriptors, but does not normally have direct access to the mbuf chain.

Use newly minted device_is_attached rather than device_is_alive to see if attach succeeded. device_is_alive just tells us that probe succeeded. Since we were using it to do things like detach net interfaces, this caused problems when there were errors in the attach routine. Symptoms of problem reported by: martin blapp

Revise attach/detach resource cleanup - Unconditionally call *_stop() if device is in the tree. This is to prevent callouts from happening after the device is gone. Checks for bus_child_present() should be added in the future to keep from touching potentially non-existent hardware in *_detach(). Found by iedowse@. - Always check for and free miibus children, even if the device is not in the tree since some failure cases could have gotten here. - Call ether_ifdetach() in the irq setup failure case - ti(4), xl(4): move ifmedia_init() calls to the beginning of attach so that ifmedia_removeall() can be unconditionally called on detach. There is no way to detect whether ifmedia has been initialized without using a separate variable (as tl(4) does). - Add comments to indicate assumptions of code path

Revert part of revision 1.97 by calling dc_stop() unconditionally in dc_detach() instead of only calling it if the hardware is preset. This is a workaround for page faults in softclock() after a `dc' device was detached, caused by not disabling a timer before freeing its memory. The bus_child_present() checks should probably be re-added later, but only to avoid the hardware accesses and not the other resource cleanups in dc_stop(). Approved by: njl

Clean up locking and resource management for pci/if_* - Remove locking of the softc in the attach method, instead depending on bus_setup_intr being at the end of attach (delaying interrupt enable until after ether_ifattach is called) - Call *_detach directly in the error case of attach, depending on checking in detach to only free resources that were allocated. This puts all resource freeing in one place, avoiding thinkos that lead to memory leaks. - Add bus_child_present check to calls to *_stop in the detach method to be sure hw is present before touching its registers. - Remove bzero softc calls since device_t should do this for us. - dc: move interrupt allocation back where it was before. It was unnecessary to move it. This reverts part of 1.88 - rl: move irq allocation before ether_ifattach. Problems might have been caused by allocating the irq after enabling interrupts on the card. - rl: call rl_stop before ether_ifdetach - sf: call sf_stop before ether_ifdetach - sis: add missed free of sis_tag - sis: check errors from tag creation - sis: move dmamem_alloc and dmamap_load to happen at same time as tag creation - sk: remove duplicate initialization of sk_dev - ste: add missed bus_generic_detach - ti: call ti_stop before ether_ifdetach - ti: add missed error setting in ti_rdata alloc failure - vr: add missed error setting in I/O, memory mapping cases - xl: add missed error setting in I/O, memory mapping cases - xl: remove multi-level goto on attach failure - xl: move dmamem_alloc and dmamap_load to happen at same time as tag creation - Calls to free(9) are unconditional because it is valid to call free with a null pointer.

Dynamically configure the width of the srom. This code comes from OpenBSD who got the code (or the idea) from the NetBSD tlp driver. This gets some cardbus dc cards working (either completely or nearly so). It also appears to get additional pci cards working, without breaking working ones. # Maybe some additional work is needed here. Also, the cardbus attachment # might need to match on the CIS rather than on the vendor/device so we have # a finer level of detail as to what the card is. Technically, the # vendor/device fields are undefined for CardBus (even though most cards are # using common silicon with pci models).

Add VLAN for the dc(4) driver (ie long frame). The patch is 2 parts. One to notify the system that the MTU for VLAN can be 1500 so the vlan will automatically be configured with a 1500 MTU the other is to ignore the error case if the received frame is to long. The frame size notification came from code in the SIS driver, and the support for long frames derived from the NetBSD Tulip driver.

Fix the "conexant chips don't work in full duplexmode" problem. According to Phil Kernick: "The problem is that in full duplex mode, the Conexant chip always reports a carrier lost error, even when the frame is successfully sent. So, if we have a Conexant chip, then ignore carrier lost when in full duplex mode." Since the Xircom chips seem to have the same issue and since we already have a workaround for this, just expand the workaround test to also check for DC_IS_CONEXANT().

Device Polling code for -current.
Non-SMP, i386-only, no polling in the idle loop at the moment.
To use this code you must compile a kernel with
options DEVICE_POLLING
and at runtime enable polling with
sysctl kern.polling.enable=1
The percentage of CPU reserved to userland can be set with
sysctl kern.polling.user_frac=NN (default is 50)
while the remainder is used by polling device drivers and netisr's.
These are the only two variables that you should need to touch. There
are a few more parameters in kern.polling but the default values
are adequate for all purposes. See the code in kern_poll.c for
more details on them.
Polling in the idle loop will be implemented shortly by introducing
a kernel thread which does the job. Until then, the amount of CPU
dedicated to polling will never exceed (100-user_frac).
The equivalent (actually, better) code for -stable is at
http://info.iet.unipi.it/~luigi/polling/
and also supports polling in the idle loop.
NOTE to Alpha developers:
There is really nothing in this code that is i386-specific.
If you move the 2 lines supporting the new option from
sys/conf/{files,options}.i386 to sys/conf/{files,options} I am
pretty sure that this should work on the Alpha as well, just that
I do not have a suitable test box to try it. If someone feels like
trying it, I would appreciate it.
NOTE to other developers:
sure some things could be done better, and as always I am open to
constructive criticism, which a few of you have already given and
I greatly appreciated.
However, before proposing radical architectural changes, please
take some time to possibly try out this code, or at the very least
read the comments in kern_poll.c, especially re. the reason why I
am using a soft netisr and cannot (I believe) replace it with a
simple timeout.

MFC (done now because the code is slightly different from the one in -current): avoid an unnecessary copy when the packet is already in a single buffer. With this one-line patch, a 750MHz box goes from 128kpps to 148kpps (full wire speed) even with NICs that require packets in a single mbuf. Trivia: the 21143, which can handle multiple buffers, seems to introduce extra delay between packets when they are split over multiple tx descriptors. So if you are in this situation and have CPU cycles to burn, doing the copy is the only way to achieve wire speed (short of arranging tx descriptors as an array instead of a linked list).

Move the clearing of IFF_RUNNING early in *_stop(), before actually freeing resources (IFF_RUNNING means resources _are_ allocated). Because *_stop() is not protected by splimp(), and it is not always called at splimp() (e.g. from *_shutdown()), the old code could potentially cause a panic at shutdown in the very rare case you get an interrupt from a device sharing the same IRQ line in the middle of *_stop(). With polling enabled, this "rare" case become slightly more frequent because clock interrupts can also hit you in the middle of *_stop(). Note that this was a bug in the original drivers, not in the polling code. Note also that some other drivers (not all) have a similar bug. The code in CURRENT seems to be safe because *_stop() is wrapped in LOCK/UNLOCK calls. Maybe it would be more robust to use splimp() around *_stop() as well.

Make sure interrupts remain disabled once you reinitialize an interface on which you have enabled polling. This fixes the problem reported by a few people who enabled polling from /etc/sysctl.conf . Fixing the "fxp" driver was interesting: as a side effect of the initialization, the chip turns interrupts on, and I was misled in believing the opposite by the "Enable interrupts" comment in the code. So i decided to make the code explicitly turn interrupts off even in the "sis" driver which already had the correct code. You never know. Note-to-self: never make assumptions on how things should work. Note-to-others: did I test this case ? Yes, on a "sis" and "dc" board, (the code for the latter was unintentionally lost during the final code cleanup). I forgot to reproduce the actual problem on the "fxp", because the interface was already initialized when i turned polling on.

As approved by the Release Engineer, here comes the code for polling
in network device drivers (x86, non-SMP only at the moment, for
reasons that I have extensively explained on the -net mailing list).
This code lets network devices operate in a semi-polling mode,
which makes systems much more resilient to attacks and overloads.
If you don't enable it with an appropriate kernel option, your
kernel will be exactly the same as before this commit. No userland
code is affected.
To use polling you have to put the following options in your kernel
config file:
options DEVICE_POLLING
options HZ=1000 # not compulsory but strongly recommended
and enable it at runtime as follows (by default it is disabled):
sysctl kern.polling.enable=1
There are basically no other tunables related to this code,
though you might have a look at "sysctl kern.polling" to see
what other variables are there.
The device drivers supported at the moment are "dc", "fxp" and
"sis", with more to come (but this code only makes sense for 100M
and Gigabit devices). Unmodified drivers will continue to operate
as before.
Under little or moderate load you should see no difference in the
behaviour of your system. Under load, you should experience a
moderate improvement in peak performance, and a lot more stability
and responsiveness.

Per jlemon request, reintroduce some printf() when an mbuf allocation fails, and fix (i hope) a couple of style bugs. I believe these printf() are extremely dangerous because now they can occur on every incoming packet and are not rate limited. They were meant to warn the sysadmin about lack of resources, but now they can become a nice way to panic your system under load. Other drivers (e.g. the fxp driver) have nothing like this. There is a pending discussion on putting this kind of warnings elsewhere, and I hope we can fix this soon.

For i386 architecture, remove an expensive m_devget() (and the underlying unaligned bcopy) on incoming packets that are already available (albeit unaligned) in a buffer. The performance improvement varies, depending on CPU and memory speed, but can be quite large especially on slow CPUs. I have seen over 50% increase on forwarding speed on the sis driver for the 486/133 (embedded systems), which does exactly the same thing. The behaviour is controlled by a sysctl variable, hw.dc_quick which defaults to 1. Set it to 0 to restore the old behaviour. After running a few experiments (in userland, though) I am convinced that doing the m_devget() is detrimental to performance in almost all cases. Even if your CPU has degraded performance with misaligned data, the bcopy() in the driver has the same overhead due to misaligment as the one that you save in the uiomove(), plus you do one extra copy and pollute the cache. But more often than not, you do not even have to touch the payload, e.g. when you are forwarding packets, and even in the often-cited case of NFS, you often end up passing a pointer to the payload to the disk controller. In any case, you can play with the sysctl variable to toggle between the two behaviours, and see if it makes a difference. MFC-after: 3 days

Deal with the condition where we lose link in the middle of transmitting a bunch of frames. In this case, the dc_link flag is cleared, and dc_start() stops draining the if_snd send queue, which results in lots of 'no buffers available' errors being reported to applications. The whole idea behind not draining the send queue until the link comes up was to avoid having the gratuitous ARP being lost while we're waiting for autoneg to complete after the interface is first brought up. As an optimization, change the test in dc_start() so that we only bail if dc_link is not set _and_ there are less than 10 packets in the send queue. If the queue has many frames in it, we need to drain them. If the queue has a small number of frames in it, we can hold off on sending them until the link comes up. MFC after: 1 week

Change m_devget()'s outdated and unused `offset' argument to actually mean something: offset into the first mbuf of the target chain before copying the source data over. Make drivers using m_devget() with a first argument "data - ETHER_ALIGN" to use the offset argument to pass ETHER_ALIGN in. The way it was previously done is potentially dangerous if the source data was at the top of a page and the offset caused the previous page to be copied (if the previous page has not yet been appropriately mapped). The old `offset' argument in m_devget() is not used anywhere (it's always 0) and dates back to ~1995 (and earlier?) when support for ethernet trailers existed. With that support gone, it was merely collecting dust. Tested on alpha by: jlemon Partially submitted by: jlemon Reviewed by: jlemon MFC after: 3 weeks

Add a check in the interrupt service routine to return quickly in case there is nothing to do. This happens normally when the card shares the interrupt line with other devices. This code saves a couple of microseconds per interrupt even on a fast CPU. You normally would not care, except under heavy tinygram traffic where you can have some 50-100.000 interrupts per second... On passing, correct a spelling error.

Bug fixes that I've put together while working on a project in the office:
if_vr: handle the case where vr_encap() returns failure: bust out of the
packet sending loop instead of panicking. Also add some missing
newlines to some printf()s.
if_dc: The miibus_read and miibus_write methods keep swapping in and
out of MII mode by fiddling with CSR6 for cards with MII PHYs.
This is a hack to support the original Macronix 98713 card which
has built-in NWAY that uses an MII-like management interface
even though it uses serial transceivers. Conditionalize this
so that we only do this on 98713 chips, since it does bad things
to genuine tulip chips (and maybe other clones).

Implement MTX_RECURSE flag for mtx_init(). All calls to mtx_init() for mutexes that recurse must now include the MTX_RECURSE bit in the flag argument variable. This change is in preparation for an upcoming (further) mutex API cleanup. The witness code will call panic() if a lock is found to recurse but the MTX_RECURSE bit was not set during the lock's initialization. The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to MTX_RECURSED, which is more appropriate given its meaning. The following locks have been made "recursive," thus far: eventhandler, Giant, callout, sched_lock, possibly some others declared in the architecture-specific code, all of the network card driver locks in pci/, as well as some other locks in dev/ stuff that I've found to be recursive.

I should eventually convert the other PCI drivers to do this; for now, these three are ones which I know need power state handling.

Yet another bug fix/optimization for the Davicom DM9100/9102: increase the PCI latency timer value to 0x80. Davicom's Linux driver does this, and it drastically reduces the number of TX underruns in my tests. (Note: this is done only for the Davicom chips. I'm not sure it's a good idea to do it for all of them.) Again, still waiting on confirmation before merging to stable.

Set the DC_TX_INTR_ALWAYS and DC_TX_STORENFWD flags for the Davicom DM9100/DM9102 chips. Do not set DC_TX_ONE. The DC_TX_USE_TX_INTR flag causes dc_encap() to set the 'interrupt on TX completion' bit only once every 64 packets. This is an attempt to reduce the number of interrupts generated by the chip. You're supposed to get a 'no more TX buffers left' interrupt once you hit the last packet whether you ask for one or not, however it seems the Davicom chip doesn't generate this interrupt, or at least it doesn't generate it under the same circumstances. The result is that if you transmit n packets, where n is less than 64, and then wait 5 seconds, you'll get a watchdog timeout whether you want one or not. The DC_TX_INTR_ALWAYS causes dc_encap() to request an interrupt for every frame. I'm still waiting on confirmation from a couple of users to see if this fixes their problems with the Davicom DM9102 before I merge this into -stable, but this fixed the problem for me in my own testing so I'm willing to make the change to -current right away.

Add support for parsing the media blocks from the SROM on 21143 adapters. This is necessary in order to make this driver work with the built-in ethernet on the alpha Miata machines. These systems have a 21143-PC chip on-board and optional daughtercards with either a 10/100 MII transceiver or a 10baseT/10base2 transceiver. In both cases, you need to twiddle the GPIO bits on the controller in order to turn the transceivers on, and you have to read the media info from the SROM in order to find out what bits to twiddle.

When I tweaked if_dc.c to alter the polling interval for non-MII 21143 chips, I accidentally removed the DC_MII_REDUCED_POLL flag for all 21143 cards. This caused problems with timer-instigated TCP retransmits, which happened to occur at the same time as an MII poll tick on MII-based cards (e.g. D-Link DFE-570TX). Fixed this, plus made some other cleanups. The autoneg fixes for the non-MII cards still work. Also tested the PNIC II now that I have one again.

Rework the support for the internal autonegotiation on the 21143 and workalike chips (Macronix 98713A/98715 and PNIC II). Timing is somewhat critical: you need to bring the link as soon as possible after NWAY is done, and the old one second polling interval was too long. Now we poll every 10th of a second until NWAY completes (at which point we return to the 1 second interval again to keep an eye on the link state). I tested all the other cards I had on hand to make sure I didn't bust any of them and they seem to work (including the MII-based 21143 card). This should fix some autoneg problems with DE500-BA cards and the built-in 10/100 ethernet on some alpha systems. (Now before anyone asks why I never noticed this before, the old code worked just find with the Intel swich I used for testing back in NY. Apparently not all switches are as picky about the timing.)

Move code to handle BPF and bridging for incoming Ethernet packets out of the individual drivers and into the common routine ether_input(). Also, remove the (incomplete) hack for matching ethernet headers in the ip_fw code. The good news: net result of 1016 lines removed, and this should make bridging now work with *all* Ethernet drivers. The bad news: it's nearly impossible to test every driver, especially for bridging, and I was unable to get much testing help on the mailing lists. Reviewed by: freebsd-net

Depend on miibus. Note that if_aue doesn't strictly depend on usb because it uses the method interface for calls rather than using internal symbols, and because it's a child driver of usb and therefore will not try and do anything unless the parent usb code is loaded at some point. if_aue does strictly depend on miibus as it will fail to link if it is missing.

Add support for the Davicom DM9102A 10/100 ethernet controller chip. This is just to make sure we initialize the chip correctly: we need to make the sure the port select bit in CSR6 is set properly so that we use the internal PHY for 10/100 support. (The eval boards I have also include an external HomePNA PHY, but I need to play with that more before I can support it.)

Reintroduce the dc_coal() workaround routine for coalescing outbound packets into a single buffer, and set the DC_TX_COALESCE flag for the Davicom DM9102 chip. I thought I had escaped this problem, but... This chip appears to silently corrupt or discard transmitted frames when using scatter/gather DMA (i.e. DMAing each packet fragment in place with a separate descriptor). The only way to insure reliable transmission is to coalesce transmitted packets into a single cluster buffer. (There may also be an alignment constraint here, but mbuf cluster buffers are naturally aligned on 2K boundaries, which seems to be good enough.) The DM9102 driver for Linux written by Davicom also uses this workaround. Unfortunately, the Davicom datasheet has no errata section describing this or any other apparently known defect.

It appears that under certain circumstances that I still can't quite pin down, the dc driver and receiver can fall out of sync with one another, resulting in a condition where the chip continues to receive packets but the driver never notices. Normally, the receive handler checks each descriptor starting from the current producer index to see if the chip has relinquished ownership, indicating that a packet has been received. The driver hands the packet off to ether_input() and then prepares the descriptor to receive another frame before moving on to the next descriptor in the ring. But sometimes, the chip appears to skip a descriptor. This leaves the driver testing the status word in a descriptor that never gets updated. The driver still gets "RX done" interrupts but never advances further into the RX ring, until the ring fills up and the chip interrupts again to signal an error condition. Sometimes, the driver will remain in this desynchronized state, resulting in spotty performance until the interface is reset. Fortunately, it's fairly simple to detect this condition: if we call the rxeof routine but the number of received packets doesn't increase, we suspect that there could be a problem. In this case, we call a new routine called dc_rx_resync(), which scans ahead in the RX ring to see if there's a frame waiting for us somewhere beyond that the driver thinks is the current producer index. If it finds one, it bumps up the index and calls the rxeof handler again to snarf up the packet and bring the driver back in sync with the chip. (It may actually do this several times in the event that there's more than one "hole" in the ring.) So far the only card supported by if_dc which has exhibited this problem is a LinkSys LNE100TX v2.0 (82c115 PNIC II), and it only seems to happen on one particular system, however the fix is general enough and has low enough overhead that we may as well apply it for all supported chipsets. I also implemented the same fix for the 3Com xl driver, which is apparently vulnerable to the same problem. Problem originally noted and patch tested by: Matt Dillon

Fix some problems reported by Mike Pritchard: - Add a flag DC_TX_INTR_ALWAYS which causes the transmit code to request a TX done interrupt for every packet. The PNIC seems to need this to insure that the sent TX buffers get reaped in a timely fashion. - Try to unreset the SIA as soon as possible after resetting the whole chip. - Change dcphy to support either 10/100 or 10Mbps only NICs. The built-in 21143 ethernet in Compaq Presario machines is 10Mbps only and it doesn't work right if we try to advertise 100Mbps modes during autoneg. When restricted to only 10mbps modes, it works fine. Note that for now, I detect this condition by checking the PCI subsystem ID on this NIC (which has a Compaq vendor/device ID). Yes, I know that's what the SROM is supposed to be for. I'm deliberately ignoring the SROM wherever possible. Sue me. The latter two fixes allow if_dc to work correctly with the built-in ethernet on certain Compaq Presario boxes. There are liable to be quite a few people using these as their home systems who might want to try FreeBSD; may as well be nice to them. Now if anybody out there has an Alpha miata with 10Mbps ethernet and can show me the output from pciconf -l on their system, I'd be grateful.

Tweak the DC_REDUCED_MII_POLL code in dc_mii_tick() for the DC_IS_INTEL() case. The idea is to reduce how often we call mii_tick(), however currently it may not be called often enough, which prevents autonegotiation from being driven correctly. This should improve the chances of successfully autonegotiating media settings on non-MII 21143 NICs. (Still waiting for confirmation from some testers, but the code is clearly wrong in any case.)

Add the if_dc driver and remove all of the al, ax, dm, pn and mx drivers which it replaces. The new driver supports all of the chips supported by the ones it replaces, as well as many DEC/Intel 21143 10/100 cards. This also completes my quest to convert things to miibus and add Alpha support.
