I was pretty much just guessing that "1518" means they were putting out
Ethernet packets with 1518 bytes of data.  Is this actually the case? If
so, it's a Bad Thing because the Ethernet standard says Ethernet packets
should have at most 1500 bytes of data; in that case, IBM should stop
doing it - end of problem.  (Did the VAXes complain about the packets as
well? If not, it could just be because the Intel 82586 that Sun uses, or
the driver than Sun provides for it, is more willing to complain about
what it thinks of as Bad Things than the VAXes hardware or driver.)
