Summary

Prior to this patch, events on interfaces that couldn't possibly be part of a PF ALTQ configuration, such as vlan(4), would trigger a copy-existing / install-new / teardown-old PF ALTQ configuration cycle. This would result in needlessly lengthy vlan(4) creation times on systems with active PF configurations that had a large number (hundreds or thousands) of queues. On such systems that also employ hundreds or thousands of vlan(4) interfaces, the time required to create those interfaces became untenable.

Test Plan

Tested with a pf.conf containing ~4k queues. vlan(4) creation times are reduced from ~200ms each to < 10ms each.
