Ok, since I had some troubles before, I torture tested it, and it failed.
So now you are going to be very intested in 'how' :)

- The situation: Transfer a *laaaarge* file from a Sparc20 with a hme0
  (100 mbit) card to a Linux machine with a 3c595, storing it in
  /dev/null.

- First of all, my switch at home (a 'lantech mini-switch') does not
  recognize full duplex on the 3com cards. So I let them at half-duplex in
  order to avoid frame errors. When I force the card into full-duplex the
  switch still sees this as half-duplex. The switch does recognize the
  full duplex on the Sun hme card without any forcing, they just
  autonegotiate it.

- The ftp transfer above hangs the 3c595 completely. I get the following
  messages:
