We have a custom MPC5200B board with an LXT972. We are having problems
with the network. When we try to mount the root via NFS, we get:

If we boot from USB, we can prove the NFS server is operational, but
we do get 'server: about do a switch' errors.

Using iperf, we have found the network to be really slow (1Mbps).
iperf between 2 linux PCs on the same network is fine.
Any help would be appreciated.
Thanks,
