Description of problem:
Gigabit ethernet card resumes from Sleep state in 100Mbs mode.

Version-Release number of selected component (if applicable):
eth0: PCI RTL8169sb Gigabit ethernet card (connected, 1000Mbps mode)
eth1: Onboard Intel 10/100 ethernet (unconnected)
(dmesg indicated it had renamed eth0 as eth1)
Netgear DS608 8-port Gigabit switch.

How reproducible:
Every time

Steps to Reproduce:
1. eth0 is in 1000Mbps mode
2. put system in Sleep mode (eth0 switches to 100Mbps mode according to switch)
3. wake up

Actual results:
eth0 remained in 100Mbps mode after wake up

Expected results:
eth0 should have renegotiated to 1000Mbps

Additional info:
"ethtool -s eth0 autoneg on" after sleep causes the port to go in 1000Mbps again.
