sungem: improve ethtool output with internal pcs and serdes (fbf0229e) · Commits · 戴 / test

From: Hermann Lauer <Hermann.Lauer@iwr.uni-heidelberg.de> 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.
