[tulip] EtherExpress Mobile fails to negotiate 100Mbps

Media table was updated. Card is manufactured 08/21/1998 according to
DOS based utility that came with the card.

Below is the latest dump from 'tulip-diag -eee', again when the card is
connected to 100Mbps full duplex capable switch (Netgear FVS318). Also,
I just realised that the WinNT drivers are not working at 100Mbps
either.
