OK, I'm waiting on it.

I didn't see this, I musr have missed it.

It's not 'tag' which makes me unconfortable, it's 'pf'. This has nothing
to do with the PF code once moved to uipc_mbuf2.c.
It's used by both packets classifiers (pf, ipf, other classifiers) and
tag consumers (altq, ipsec). 
As far as I can tell, m_tag related functions are all prefixed with m_tag,
not tag. And a m_tag prefix for these functions looks fine to
me (m_tag_name2tag(), m_tag_tag2name(), etc), as they're really related to
m_tag too.
