3meg Ethernet byte order?

[Don Speck]

    Some of our neighbors run BRL VAX Unix and wanted to network
to our machines, without buying anything.  So, I handed them an
obsolete Xerox 3-megabit Ethernet board from our stockpile and
connected it up for them.

    Their vax won't talk to the two of ours that are on that net.
We tried a 3-meg board in another neighbor's Eunice vax and it
won't talk to us either - but it *will* talk to the BRL Unix vax.

    Our if_en.c has conditionals to swab header and data of IP
packets, all packets, or none.	SWABALL is what's currently in
effect.  The BRL Unix machine does not appear to be doing any
byte swabbing at all.

    One of us is using the wrong byte order.  Which of us is it?
Does it have anything to do with the V-kernel 'enetfilter' hooks
scattered throughout if_en.c?
