Just now I have only mii-tool on my machine.
'mii-tool -R' (I assume that should do the same as 'mii-diag -R')
DOES reset my NIC, so that I get a "link ok" (before it was "no
link").
After 'ifdown eth0' and 'ifup eth0' I have a functional connection.

Thanks for that hint.

DB> Using 'mii-diag' or 'vortex-diag' is a good start

'mii-tool -v eth0' says:
eth0: no link
  product info: vendor 00:00:00, model 0 rev 0
  basic mode:   autonegotiation enabled
  basic status: no link
  capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  100baseTx-FD 10baseT-FD
  link partner: 100baseTx-HD 10baseT-HD

After 'mii-tool -R', 'mii-tool -v eth0' says:
eth0: 100 Mbit, half duplex, link ok
  product info: vendor 00:00:00, model 0 rev 0
  basic mode:   100 Mbit, half duplex
  basic status: link ok
  capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  link partner: 100baseTx-HD 10baseT-HD

Looking at the "advertising" lines, I get the feeling that I've got
some Duplex problem...
Or do I have a problem in Understanding this?
