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.
