I was under the impression that the packet priority was always set to 3 prior to the pf ruleset evaluation (ignoring VLAN and CARP for a moment), and that 'set prio' on an inbound rule only affected returning traffic that matched the state entry. Here's an artificial example:
pass out on $wan pass in on $lan set prio 7 What will be the priority of outbound packets on the $wan interface, 3 or 7? Looking at the code in pf.c, the priority is copied to m->m_pkthdr.pf.prio, but I'm not sure where this value is initialized or reset.
