Two problems I hope to solve:
1. The switch being used has autoneg off and has port set to 100 full duplex.
2. Many times NIC fails to come up properly during PXE boot:
r8169: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready
I can't use ethtool to disable autoneg because the nic driver is built
into a bzImage. The root fs is currently being mounted via nfs during
pxeboot at speed 10, half-duplex. In the past for sk98lin driver I
could pass a kernel module parameter sk98lin.ConType=100FD on the
kernel boot line.
I looked at the r8169.c and tried to hard code the default to autoneg
off but that didn't work.

Any other ideas?
