<jwilkins@madscience.dyndns.org>, we don't declare "ether_hostton()" on
FreeBSD - it's declared in <net/ethernet.h> in 3.0 and later, and is
declared with the first argument as "const char *" in 4.0 and later so
that if we declare it with the first argument as "char *" we get errors.
(If we declare it with "const char *", you get errors on FreeBSD 3.x and
other systems that *don't* declare it with "const char *".)
XXX - should it go, instead, into "lbl/os-XXX.h" files, for those OS
versions that don't declare it, and not be declared at all here?
painful when upgrading old libpcap to tcpdump.org pcap (function rename
usually requires shlib major number bump, while api addition only require
minor)
./configure --enable-ipv6 (requires getaddrinfo(3) and getnameinfo(3)).
TODO: make it work even without getaddrinfo(3) or getnameinfo(3)
(or, tcpdump/configure.in should provide alternative version by
AC_REPLACE_FUNCS)
TODO: make IPv6 filtering code work by default
TODO: make "protochain" friendly with optimization
