Keyword substitution: kv
Default branch: MAIN

Handling frames that vlan id is 0 as non-VLAN frames
even if a vlan tag is stripped by harware offloading

vlan: Register vlan_ifdetach to ether_ifdetach hook

vlan: Register the callback to update link-state of vlan I/F
to link-state change hook

The callback is registered in every vlan I/F even if the parent
interface is the same. Therefore it is not needed to search the
vlan I/F by the parent interface unlike the previous callback.

vlan: match the interface link state with that of the parent

Now addresses on a vlan will detach and undergo duplicate address
dectection on link state changes just as on a standard interface.

Mostly style, and add a bunch of KASSERTs.

  Fix a bug that a vlan packet which has priority or CFI bit in the tag causes
panic.
  Revert part of if_bge.c 1.312. It's not required to mask other than VLAN ID
bits in VLAN tag.
  Revert if_wmreg.h 1.104 and if_wm.c 1.542. It's not required to mask other
than VLAN ID bits in VLAN tag.
No functional change:
  - u_int16_t -> uint16_t
  - u_short -> uint16_t
  - tag_hash_func -> vlan_tag_hash
  - 0 -> NULL because vlr_parent is a pointer.

When an Ethernet interface detaches, unconfigure any VLANs associated
with it.

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).

Port the multicast handling to NetBSD correctly.

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.
