This shouldn't really be required.

Look Fine.

Hmmm, that's curious.  I'll check if I have a rev. 17 chip to see if the
transceiver is misreported.

Yup, looks like a fatal bus error.
It appears to be a parity error.

Try moving the card to a different slot, or gently cleaning the contacts.

Uhhmmm, it's a ADMtek Centaur-P chip.  There is likely a PCI subsystem
ID programmed into the EEPROM that identifies the board as having a
Linksys label, but that has no impact on operation.

Send me the following
   The exact name and number on the NIC box or printing (including e.g. "v5.1")
   The entry from 'cat /proc/pci' or 'lspci -n -v'.
   The output of 'tulip-diag -eee'.

Nope.  The bus errors are reporting a hardware problem.  You might be
able to catch and show the error state with 'tulip-diag -a'.
