I have a nice rack of servers to which I've recently added a gigabit switch. Flow control is enabled on the the relevant switch ports. The servers with Tigon (tg3) Ethernet automatically enable flow control, but the servers with Intel e1000 Ethernet don't, and I believe this is causing problems when doing things like UDP NFS service to 100Mbit devices. (Kickstart-over-NFS is terribly slow, for example.) Is there a reason that e1000 doesn't enable flow control when the switch advertises it as the tg3 driver does? Is there any way to force it to negotiate flow control with the switch? - J<
