FILE REMOVED 

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.

Fix up the autonegotiation a little:

- Get rid of all 100baseT4 references; the Macronix chips don't really
  support it, and we shouldn't give the autonegotiation code an opportunity
  to select it as the current media when we haven't even ifmedia_add()ed
  IFM_100_T4 as a valid selection.

- Change the non-MII autonegotiation routine to use the link partner
  code word bits from CSR12 (10baseT status), which is the standard
  DEC 21x4x way of detecting link partner ability instead of using the
  Macronix-specific NWAY status register at CSR20.

This should fix problems with 98715A or 82c115 PNIC II chips (LinkSys
LNE100TX v2.0) incorrectly negotiationg 100baseT4 with some switches
or hubs and then crashing due to 100baseT4 not being a valid mode.

Problem found and fix tested by: Roger Hardiman <roger@cs.strath.ac.uk>

Convert the mx driver to miibus.

In order to make this work, I created a pseudo-PHY driver to deal with
Macronix chips that use the built-in NWAY support and symbol mode port.
This is actually all of them, with the exception of the original MX98713
which presents its NWAY support via the MII serial interface.

The mxphy driver actually manipulates the controller registers directly
rather than using the miibus_readreg()/miibus_writereg() bus interface
since there are no MII registers to read. The mx driver itself pretends
that the NWAY interface is a PHY locayed at MII address 31 for the sole
purpose of allowing the mxphy_probe() routine to know when it needs to
attach to a host controller.

As suggested by phk, unconditionalize BPF support in these drivers. Since
there are stubs compiled into the kernel if BPF support is not enabled,
there aren't any problems with unresolved symbols. The modules in /modules
are compiled with BPF support enabled anyway, so the most this will do is
bloat GENERIC a little.

Tweak these for what I hope is the last time: change the DRIVER_MODULE()
declaration for the interface driver from "foo" to "if_foo" but leave the
declaration for the miibus attached to the interface driver alone. This
lets the internal module name be "if_foo" while still allowing the miibus
instances to attach to "foo."

This should allow ifconfig to autoload driver modules again without
breaking the miibus attach.

Un-do the changes to the DRIVER_MODULE() declarations in these drivers.
This whole idea isn't going to work until somebody makes the bus/kld
code smarter. The idea here is to change the module's internal name
from "foo" to "if_foo" so that ifconfig can tell a network driver from
a non-network one. However doing this doesn't work correctly no matter
how you slice it. For everything to work, you have to change the name
in both the driver_t struct and the DRIVER_MODULE() declaration. The
problems are:

- If you change the name in both places, then the kernel thinks that
  the device's name is now "if_foo", so you get things like:

if_foo0: <FOO ethernet> irq foo at device foo on pcifoo
if_foo0: Ethernet address: foo:foo:foo:foo:foo:foo

  This is bogus. Now the device name doesn't agree with the logical
  interface name. There's no reason for this, and it violates the
  principle of least astonishment.

- If you leave the name in the driver_t struct as "foo" and only
  change the names in the DRIVER_MODULE() declaration to "if_foo" then
  attaching drivers to child devices doesn't work because the names don't
  agree. This breaks miibus: drivers that need to have miibuses and PHY
  drivers attached never get them.

In other words: damned if you do, damned if you don't.

This needs to be thought through some more. Since the drivers that
use miibus are broken, I have to change these all back in order to
make them work again. Yes this will stop ifconfig from being able
to demand load driver modules. On the whole, I'd rather have that
than having the drivers not work at all.

Cast a couple of pointers to ints via 'uintptr_t' rather than 'unsigned

Grrr! The PNIC II's multicast hash table is only 128 bits wide, not 512
like the original PNIC and the MX98715A (from which the PNIC II is derived).
This requires special handling. Save the card type, and in mx_calchash(),
if we see that the card is a PNIC, return only the low 7 bits of the
hash instead of the low 9 bits.

Fix support for the PNIC II. Earlier I had assumed that the PNIC II was
similar to the PNIC I (supported by the pn driver). In fact, it's really
a Macronix 98715A with wake on LAN support added. According to LinkSys,
the PNIC II was jointly developed by Lite-On and Macronis. I get the
feeling Macronix did most of the work. (The datasheet has the Macronix
logo on it, and is in fact nearly identical to the 98715 datasheet, except
for the extra wake on LAN registers.) In any case, the PNIC II works just
fine with the Macronix driver.

The changes are:

- Move PCI ID for the PNIC II from the pn driver to the mx driver.
- Mention PNIC II support in mx.4.
- Mention PNIC II support in RELNOTES.TXT and HARDWARE.TXT.

Simplify the COMPAT_PCI_DRIVER/DATA_SET hack.  We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

Tweak the Macronix driver to hopefully make it more reliable:

- Change to the same transmit scheme as the PNIC driver.
- Dynamically set the cache alignment, and set burst size the same as
  the PNIC driver in mx_init().
- Enable 'store and forward' mode by default. This is the slowest option
  and it does reduce 100Mbps performance somewhat, but it's the most
  reliable setting I can find. I'm more interested in having the driver
  work reliably than trying to squeeze the best performance out of it.
  The reason I'm doing this is that on *some* systems you may see a lot
  of transmit underruns (which I can't explain: these are *fast* test
  systems) and these errors seem to cause unusual and decidedly
  non-tulip-like behavior. In normal 10Mbps mode, performance is fine
  (you can easily saturate a 10Mbps link).

Also tweak some of the other drivers:

- Increase the size of the TX ring for the Winbond, ASIX, VIA Rhine
  and PNIC drivers.
- Set a larger value for ifq_maxlen in the ThunderLAN driver. The setting
  of TL_TX_LIST_CNT - 1 is too low (the ThunderLAN driver only allocates
  20 transmit descriptors, and I don't want to fiddle with that now
  because the ThunderLAN's descriptor structure is an oddball size
  compared to the others).

Put back some missing chip identification code that got lost somehow
during a trek through RCS. The Macronix 98713 and 98713A both have the
same PCI device ID but different revision numbers, and we need to be
able to tell one from the other. The 98715 and 98715A chips have the
same device ID as the 98725 chip but different revision numbers, however
we lump them into the same category except when identifying them during
the PCI probe output.

The main reason we need tell the chips apart is that the Macronix app
notes say you have to write a special magic number into one of the
registers in order to put the chip in normal operating mode. The 98713
requires one magic value, while all the others require a different one.

         Rhine II chips (note: the D-Link and certain other cards
         that actually use a Rhine II chip still return the PCI
         device ID of the Rhine I. I don't know why, and it doesn't
         really matter since the driver treats both chips the same
         anyway.)

if_wb.c: Trendware TE100-PCIE and various other cards based on the

All drivers include support for ifmedia, BPF and hardware multicast
filtering.

Also updated GENERIC, LINT, RELNOTES.TXT, userconfig and
sysinstall device list.

I also have a driver for the ASIX AX88140A in the works.
