Should you increase the bytes-output statistic before vlan calls if_start,
by analogy to ether_output?  That is should you add the line I mark to
this code fragment from vlan_start?

                IFQ_ENQUEUE(&p->if_snd, m, &pktattr, error);
                if (error) {
                        /* mbuf is already freed */
                        ifp->if_oerrors++;
                        continue;
                }

>               ifp->if_obytes += m->m_pkthdr.len;
                ifp->if_opackets++;
                if ((p->if_flags & IFF_OACTIVE) == 0)
                        (*p->if_start)(p);

Possibly some more statistics deserve to be counted, too.
