gigabit requires autonegotiation, and if you force speeds you would have to force
it on both ends anyway. The above configuration is therefore not a valid
configuration.

I suggest changing the autonegotiation mask, which leaves autoneg enabled:

	ethtool -s eth0 advertise 0x20

this is supported and should accomplish what you want.
