PF processes rules from top to bottom for every packet, only aborting
the rule evaluation in the case that the "quick" keyword is used to
render a decision immediately.

If you are trying to avoid having to evaluate all of your rules on every
packet, you should read up on the "anchor" feature, which allows you to
perform a type of "subroutine call", evaluating a different ruleset upon
some condition.  You could conceivably use that to evaluate some rules
and come to a decision without having to evaluate all of the rules in a
policy.  It would take some rethinking of your existing rules, no doubt.

As far as I'm aware, PF is a layer-3 only filter, and has no ability to
filter on MAC.
