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
