Subject: [patch] sumgem: improve ethtool output with fibre card using the internal pcs and a serdes

Attached is a patch which improves the output of ethtool (see below) to
some sensefull values with a sungem fibre card which uses the 
sungem interal pcs connected to a serdes chip. The seriallink case
in the driver is untouched.

Most values are hardcoded, because gigabit fibre autoneg is anyways
limited and the driver don't really support much at the moment
with that hardware.

Please consider for inclusion or comment.
Thanks,
  Hermann
