727c88e9da 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).

141ae16656 Add support for still more cheapo 10/100 cards: Delta Electronics and
Addtron appear to have their own VIA Rhine II and RealTek 8139 boards
with custom PCI vendor and device IDs. This commit updates the PCI
vendor and device lists in the vr and rl drivers so that we can probe
the additional devices.

Found by: nosing around the PCI vendor and device code list at:

6c70e5b472 Tweak the vr_start() and vr_rxeof() routines a little to improve
performance and reliability a little. There was a condition before
where transmission would stall during periods of heavy traffic
exchange between two hosts. Also set the 'want interrupt' bit in
receive descriptor control words.

726ff6a158 An early Christmas present: add driver support for a whole bunch of
PCI fast ethernet adapters, plus man pages.

if_pn.c: Netgear FA310TX model D1, LinkSys LNE100TX, Matrox FastNIC 10/100,
         various other PNIC devices

if_mx.c: NDC Communications SOHOware SFA100 (Macronix 98713A), various
         other boards based on the Macronix 98713, 98713A, 98715, 98715A
         and 98725 chips

if_vr.c: D-Link DFE530-TX, other boards based on the VIA Rhine and
         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
         Winbond W89C840F chip (the Trendware card is identical to
         the sample boards Winbond sent me, so who knows how many
         clones there are running around)

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.
