since we inherit prio (as in, the queuing priority) from outside sources,

i. e. on vlan interfaces, it is useful to be able to match on it -
effectively matching on classification done elsewhere.
i thought i had long implemented that, but chrisz@ asking for it made
me notice that wasn't the case.
tests by chrisz, ok phessler pelikan
