[This was broken when the 4.4BSD ARP table changes were done, and never
repaired.]
Inspired by Jarle Greipsland, PR 4531; code stolen from arp.a and cleaned
up (mostly removing global variables).
XXX As pointed out in the PR, this should be in some library (libutil?),
to be usable by other servers like bootpd and dhcpd.
* don't use LOG_CONS - it's unnecessary and spams the console if syslogd
fails (a bad thing, really)
From [misc/873] by Giles Lean <giles@nemeton.com.au>:
* explain why the name lookup failed
* always send debug() via syslog(3) (unlike the PR, which added a -s flag)
* enhance the man page a bit (even in the commented out section which
is only relevant to the -DREQUIRE_TFTPBOOT case
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.
