Indeed, setsockopt(2) can only control the IP precedence of packets
generated by sockets opened locally, on this host.

Correct me if I'm wrong, but the functionality offered, e.g., by cisco
routers:

	route-map XX
	match <access-list>
	set ip precedence XX

isn't in FreeBSD.  It can be implemented as a hack to ipfw or pf, but
there is no general framework ready for use.

When making the hack, don't forget to recompute the IP checksum after
modifying the IP precedence field.
