this fixed in the figures (but still not in the text); anyway, the intention
of the ATA is that this is identical to the PHDS specification.
Remove the ...EXC_8782 constant, and change the _EXC_1201 constant to be
a simple ...EXC.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
