I've got a Dell Precision Workstation 490 with 64-bit Centos 5, fully 
updated, with an on-board Broadcom 57xx gigabit Ethernet controller, 
updated BIOS, 1 GB switch, and /var/log/messages and dmesg both claim the 
link is 100 Mb, not 1 GB.

I tried setting eth0 to mtu 9000 but got an error in going so.

What do I need to do to have the card see 1 gb?

Thanks.
