Re: [9fans] Has anyone got a 2114x ethernet card working under 4th Edition?

Ether2114x.c has a facility similar to the 'fixup' code in the linux driver,
look for the 'leaf21140' table.

If you can compile the kernel with the 'DEBUG' flag on in the driver and
bring the system up with the duff card as ether1, the debug messages on the
console and the contents of the device 'ifstats' file (will give the
SROM contents) would aid in patching the driver.

I know this is an old thread, but I just ran into this problem today with an
SMC 9332DST card and thought my experience might help others.  The broken
detection message was:

   #l0: 2114x: 0 Mbps port 0xfc80  irq 10  c0f401000000

Note that the speed and EA are both bogus.

Here's the interesting part:  I tried a newer variant of the card, an SMC
9332BDT, and it works perfectly with the 2114x driver.

The output from "pci" for *both* cards is identical:

   0.15.0:  02.00.00  1011/0009  10  0:0000fc81  128  1:ffbefc00  128

The Tulip chips on the 2 cards have the following markings:

   9332DST (doesn't work with 2114x driver):  21140 / DC1010BA / 21-40673-01

   9332BDT (works with 2114x driver):  21140-AE / DC1064B / 21-43864-03

I suspect transceiver or EEPROM differences may be the significant driver
issue in the case of these 2 cards rather than the variant of Tulip chip.
FWIW, I note that Don Becker's Tulip driver for Linux has an entry in
"eeprom_fixups[]" for the (broken in Plan 9) 9332DST, while I don't see
anything similar in ether2114x.c
