 This is a patched version of original function
 
 code
        /*
         * If underlying interface can not do VLAN tag insertion itself
         * then attach a packet tag that holds it.
         */
        if ((m->m_flags & M_VLANTAG) &&
            (ifp->if_capenable & IFCAP_VLAN_HWTAGGING) == 0) {
                m = ether_vlanencap(m, m->m_pkthdr.ether_vtag);
                if (m == NULL) {
                        ifp->if_oerrors++;
                        return (ENOBUFS);
                }
                m->m_flags &= ~M_VLANTAG;
        }
 
 
 was added.
 
 Iam does not test this path - haven’t net with vlan support.
 
 Code was taken from if_bridge and adapted.
