4.2 arp enhancements

[james at umcp-cs.UUCP]

As requested by Bill Shannon, we will provide ARPANET FTP access
to his 4.2bsd Address Resolution Protocol enhancement code.

They may be obtained from site MARYLAND (that's 26.2.0.57 for those
of you with old ancient host tables), using FTP login anonymous
and any password.  The file to transfer is 4.2arp, and it is exactly
as provided by Bill Shannon <sun!shannon at Berkeley>.
