I have tried this, but nothing happens... Here is what i did:

server:~# mii-tool -v --force=100baseTx-FD eth0
server:~# mii-tool -v
eth0: 10 Mbit, half duplex, no link
  product info: vendor 00:00:00, model 0 rev 0
  basic mode:   10 Mbit, half duplex
  basic status: no link
  capabilities:
  advertising:

Very strange. I have tried a different port on the hub with no change to 
the above. BTW: All other servers are at 100base-Tx. Here is some more 
output:

server:~# mii-diag -a

Any further help is greatfull.
