This is intresting. Your card reports that it is stopped while the other
report show normal values on most things. Does this change if you try and
send something (like a ping)?
Common to both reports is that the transceivers don't respond.
The functioning card reports a PHY ID of 0016 f880, wonder which chip that
is ... ?
The attached patch for the via-daig program plays with a few registers.
Run it as 'via-diag -aaeemm -I' then do a 'ifconfig eth0 down; ifconfig
eth0 up' and see if anything happens.
If this doesn't work you may want to play "guess the register". A fun
game for all ages, made more fun by using obfuscated english. There is a
datasheet here for a chip similar to the ones you have.
