Any objections to MFCing IF_HANDOFF and IF_HANDOFF_ADJ?  I'd like
there to be a common API between -stable and -current.

I'm thinking that the following macros would be sufficient for -stable:

#define IF_HANDOFF_ADJ(q, m, ifp, adj) \
		if (IF_QFULL((q))) { \
			IF_DROP((q)); \
			m_freem((m)); \
		} else { \
			(ifp)->if_obytes += (m)->m_pkthdr.len + (adj); \
			if ((m)->m_flags & M_MCAST) \
				(ifp)->if_omcasts++; \
			IF_ENQUEUE((q), (m)); \
			if (((ifp)->if_flags & IFF_OACTIVE) == 0) \
				(*(ifp)->if_start)((ifp)); \
		}
#define IF_HANDOFF(q, m, ifp) IF_HANDOFF_ADJ(q, m, ifp, 0)

Comments?

Warner
