My recollection is that the ed0 driver can return this message if it is 
failing OR if some other device on the network is sending bad packets.  If 
you are on a switched network, either your NIC or your switch is probably 
bad.  If you are on a broadcast network (hub or coax) it could be any device 
on the network.  

If the messages happen frequently, try unplugging one device at a time 
from the network to see if you can figure out which one it is.  If the 
messages don't happen often, you can probably ignore them.
