Ok, itojun, I did a quick review of the patches.
And what do I find ?

pf code (pftag_tagname2tag) moved from pf.c to uipc_mbuf2.c

What sort of joke are you trying to pull here ?

Furthermore, the patches that bring pf into IP do not use
pfil(9).  That is not acceptable.  It's there for a reason
and the reason is for things like pf to use it.  If there
is a deficiency in the interface then bring it up for
discussion.

Stop being is such a god damned rush to get this to happen,
sit back, stop, think for a while and try to do it well
rather than just get it done.
