I have 2 BCM5708s in my DL380, but they are both stuck at 100 Mb, Full Duplex, despite being plugged into a gigabit switch. I have checked the switch ports with another gigabit device, and they connect at full speed. I have tried changing the speed using the VIC from "Auto negotiate" to "1000 Mb, Full Duplex", but then the links go down.
How do I get my NICs to run at full speed?
