Sigh. That's what I so love about the UNIX community - they've come
quickly to a consensus about the right header file to include to declare
"ether_ntohost()", and you can just include the same header file, on all
platforms, and get it declared.
NOT.
I guess we should add tests for <netinet/if_ether.h> in the configure
scripts for libpcap and tcpdump, and, if it's missing, don't include it
(various distributions of Linux are, from what I can tell, among the
platforms where including it doesn't get "ether_ntohost()" declared, and
where you might or might not actually have it in the first place).
I'll check that in.

Well, the comment in "pcap-linux.c" says:
/*

It might be interesting to see what happens if you do that on a
PF_PACKET/SOCK_DGRAM socket (or to check the kernel code to see if
that'll work); if not, then it'll be normal behavior because that's all
the kernel lets you do.
