Alan, were you going to apply these or no ?

Just curious (trying to test and I wanted to make sure I'm in synch).

Trying to track down some bug.  The master process died and the remaining
ones are inactive...

This is a patch to have send_arp called with the correct information for
BSD/Solaris

It grabs the correct HW address for Linux vs. *BSD/SunOS.

 <<diff.diff>> 

I also added the HW address to the info line being printed out to the INFO
file.

Unfortunately, BSD doesn't seem to have the support for the protocol:

# send_arp dc0 64.65.195.196 00a0cc34a878 64.65.195.186 00a0cc34a878
socket: Protocol not supported

I'm currently seeing what alternatives exist.  There must be some way to do
this in BSD/Solaris.
