Eth0 stuck in 10Mb mode

[Joseph M Bironas]

This is strange, on Fedora Core 1, mii-tool does not modify the card
behavior for my 3c59x adapter anymore. It's stuck in 10baseT-FD mode,
but should easily support 100BaseTx-HD (or FD, but I'd be happy with
HD).

here's the command output:
[root at xxx /root] mii-tool --force=100baseTx-HD
[root at xxx /root] mii-tool --restart
restarting autonegotiation...
[root at xxx /root] mii-tool -v
eth0: 10 Mbit, full duplex, link ok
  product info: vendor 01:e1:c1, model 56 rev 7
  basic mode:   isolate, collision test, 10 Mbit, full duplex
  basic status: autonegotiation restarted, link ok
  capabilities:
  advertising:  100baseT4 100baseTx-FD 100baseTx-HD flow-control
  link partner: 100baseT4 100baseTx-FD 100baseTx-HD flow-control

Any help is much appreciated.

Regards,
Joseph
