  Modified files:
    sys/pci              if_xl.c if_xlreg.h 
  Log:
  Apply patch graciously provided by Jason Wright <jason@thought.net> from
  the OpenBSD group to fix a problem with the default ifmedia not being
  set properly in some cases with a 3c905B, leading to a panic in ifmedia_set().
  
  Also apply a patch to force the transmit start routine to check the
  transmitter to make sure it isn't wedged if the outbound tx queue appears
  full. This seems to cure some problems with 'watchdog timeout' errors
  cropping up in some cases. I tried to do this before by checking for the
  IFF_OACTIVE flag on entry to xl_start(), but if the IFF_OACTIVE flag is
  set, ether_output() won't even call xl_start(). It should work now.
  
  Lastly, increase the size of the TX queue from 10 descriptors to 16 to
  hopefully make it less likely that the TX queue will fill up.
