Log message:
avoid passing weird mbuf chains to pf when pushing out a veb.
pf expects the ip header to be in the first mbuf of the chain we
pass to pf_test, but in some situations the ethernet header is the
only data in the first mbuf. after we remove the ethernet header,
the first mbuf had no data in it which confused pf. fix this by
passing all packets to ip_check on output as well as input. ip input
handlers do all the necessary m_pullups.
