40606ab8f2 switch from kame-based m_aux mbuf auxiliary data, to openbsd m_tag 
implementation.  it will simplify porting across *bsd (such as kame/altq),
and make us more synchronized.  from Joel Wilsson

42a2e688fe If the parent interface can do hardware-assisted VLAN encapsulation, 
then propagate its hardware-assisted checksumming flags.

5cbdcc502b Add ALTQ support (both for the VLAN interface itself, as well as for 
being a VLAN on a ALTQ'ified interface).

53c23f549a Start out with a link name that says "802.1Q VLAN", and inherit the 
parent interface's as usual once we attach to the parent.  When we
detach from the parent, reset our link name to the "802.1Q VLAN" name.

32024e8a3d call if_alloc_sadl(). without it the following operation causes kernel panic: 
# ifconfig vlan0 create

6484f81abc We now support hw vlan tag support in network interfaces, so remote it

6e08061c2a Supports hardware 802.1q VLAN tagging, per discussion on tech-net. The tag is 
stored in a m_aux mbuf defined by AF_LINK, ETHERTYPE_VLAN.
Thanks to Jason & Itojun for the feedback.

0d0fd7718e Per discussion with Jason, change flags filter to 
(IFF_UP | IFF_BROADCAST | IFF_RUNNING | IFF_ALLMULTI | IFF_SIMPLEX)
Also, put the ifp->if_opackets++ at the rigth place so that the counter is
incremented even when the parent is OACTIVE.
Fix a bug in vlan_input where the ethernet src and dst addrs would not be
correct because we only memmove() only ifv->ifv_encaplen instead of
sizeof(struct ether_header).

3659b305e5 In vlan_config(), filter flags inherited from parent interface to 
(IFF_UP | IFF_BROADCAST | IFF_RUNNING | IFF_ALLMULTI | IFF_SIMPLEX)
Without this, if the parent is OACTIVE of PROMISC at config time, we
loose.

29fdeefaff Don't try to handle SIOCSIFADDR/SIOCADDMULTI/SIOCDELMULTI if a vlan/vlanif 
hasn't been configured (prevent a panic in arp_ifinit when setting an
IP addr with no vlan/vlanif).

96375e93ea Improve the VLAN support, in particular, handling of MTU: 
- Add a macro to compute the max frame length based on Ethertype
  and presence of FCS, and use it to validate the packet size
  in ether_input().
- Add capabilites to struct ethercom, and allow hardware drivers
  to specify that they can handle the larger hardware MTU that
  VLANs require in order to strictly conform to 802.1Q.
- Make ether_ifdetach() clear out the link address and free all of
  the Ethernet multicast structures.

Also, rearrange the VLAN driver itself in preparation to supporting
other hardware types, including FDDI (which has 802.1Q VLAN capability).

00746cb0d6 Support for 802.1Q Virtual LANs. Derived and cleaned up by 
Andy Doran <ad@netbsd.org> from the FreeBSD/OpenBSD implementation.
A few minor changes to how it all hooks into the system by me.
