[CentOS] ethtool

We've just moved one a new server from our sever room, where I built it, to the datacenter. We want to force autoneg off, and tell it gigabit and full duplex. Using ethtool, I get no errors setting the speed or duplex. HOWEVER, autoneg on works... and autoneg off utterly refuses to work, and gives: ethtool -s eth0 autoneg off Cannot set new settings: Invalid argument not setting autoneg

We're on the most current update of CentOS (ok, last kernel, that will come up on the reboot I'll do shortly), and it's a Broadcom Corporation NetXtreme II BCM5716 Gigabit Ethernet

Anyone have an idea what's going on here?
