Normally I would say that this is impossible.  The full duplex flag
should always override the media table.

Ohhhh, that's bad.  That appears to be an invalid media table entry.
Please send the output of 'tulip-diag -ee' so that we can see the raw
entry.

This is an expected entry for MII transceivers.

It's possible to overwrite the EEPROM.
By seeing the actual media table entry we might be able to figure out a
work-around without doing that.
