This is a message from the eepro100 device driver.  
That is what I was looking for.  

You need to hard-code the media selection, the autodetection doesn't work.
I think this may be true for all the oskit linux ethernet drivers.

I use this change to linux/src/drivers/net/eepro100.c for
my 100Mbs full-duplex connection.
