        sys/net/if_ethersubr.c: revision 1.255

Fix two bugs in altq_etherclassify. When scanning the mbuf chain we need
to make sure that m_next is not NULL, otherwise NULL deref. After that,
we must not touch m->m_pkthdr, given that 'm' may not be the first mbuf
of the chain anymore.

Declare mtop, and add a KASSERT to make sure it has M_PKTHDR set.
