Subject: Re: sumgem problems with initializiation order at a 1000SX SERDES card [experimental patch]

Attached is an experimental patch which made my 1000SX sungem card (with phy_serdes) working.
As suspected, reinitialising the PCS part after the global reset in gem_reinit_chip()
gets autonegotiation working and the link is established also after an ifconfig up
command now. Access through the card did not show any errors so far.

Will try to add the missing if clauses to the patch as time allows me, comments are welcome.

Hermann
