+   I'm moving towards the defined names in linux/if_ether.h for clarity.
+   The confusion between 60/64 and 1514/1518 arose because the NS8390
+   counts the 4 byte frame checksum in the incoming packet, but not
+   in the outgoing packet. 60/1514 are the correct numbers for most
+   if not all of the other NIC controllers.
