Hi!
Changes:
1. list + hash was replaced by array of hooks: its simple and faster
2. added encap setting.
"getencap" and "setencap" messages for control it:
Default =3D 1 (do the VLAN encapsulation)
0: no encapsulation, just:
m->m_flags |=3D M_VLANTAG;
m->m_pkthdr.ether_vtag =3D (vlan & EVL_VLID_MASK);
Who can test?
