rG2339ead6384e: pf: allow filtering on the receive interface
Summary

add support to pf for filtering a packet by the interface it was received
on. use the received-on IFNAME filter option on a pf.conf rule to restrict
which packet the interface had to be received on. eg:

pass out on em0 from $foo to $bar received-on fxp0

ive been running this in production for a week now. i find it particularly
usefull with interface groups.

no objections, and a few "i like"s from henning, claudio, deraadt, mpf
