  Log:
  Close PR #13665. I managed to figure out the problem, no thanks to the
  submitter, who *still* hasn't bothered to answer me back.
  
  The thing which the submitter completely failed to mention is that
  his 3c900B-TPO card has the transceiver selection in the EEPROM set
  to "auto." You can tweak the setting using the 3C90XCFG.EXE utility
  that 3Com provides with the card. I'm not sure if it's supposed to
  default to auto or if the user fiddled with it. Currently, the xl
  driver only does autoselection for 10/100 NICs (i.e. those with NWAY
  autonegotiation capabilities). For the 10baseT, 10base5, 10base2,
  10baseFL and 100baseFX cards, the driver sets the default media to
  whatever the EEPROM transceiver selector says. The problem is that
  the "auto" selection is mistakenly identified as "10/100 NWAY
  autoselection mode" and this is not handled correctly: the default
  media ends up being chosen as 100baseTX, which doesn't work because
  we've only added 10baseT media types to the ifmedia word. This leads
  to a panic in ifmedia_set() (something else which the submitter never
  bothered to mention).
  
  A workaround for this is to re-run the 3C90XCFG.EXE utility and change
  the transceiver selection to something besides "auto." I have also
  patched the driver to watch for the "auto" setting in the non-miibus
  case and select a reasonable default based on the card type instead of
  falling through to 100baseTX and exploding.
