This message is produced if the ethernet card receives a packet
that is bigger than permitted by the MTU + the size of the ethernet
header. For normal ethernet this means that packets should be <=
1514 bytes.
So, there are three ways to eliminate the the message:
1) Find the machine sending oversize packets and stop it.
2) Change the MTU on your interface using ifconfig, this
will only work if the other machines on the network expect
larget frames.
3) You could edit /usr/src/sys/net/if_ethersubr.c and remove
the code that prints this error and then recompile your
kernel.
