Checked in.

Mike S.?  Is the "sendto()" just there because libnet doesn't bind the
socket?  If so, a "send()" would work.

Mike S.?  Does the libnet code work on SunOS 4.x?  I'm not sure a
"sendto()" would work on a STREAMS NIT descriptor in 4.x.  In FreeBSD
3.4, it only works on sockets; if that's the way it's been in BSD for a
while, that might be how it was in 4.x - I don't remember support for it
being added for non-socket descriptors in 4.0.
