f23872a5c5 A network interface driver can support IFCAP_VLAN_MTU only,
without IFCAP_VLAN_HWTAGGING.  The previous version of the
leading comment in this file could lead to the opposite conclusion.

Fix some typos in the comment as well.

2d3799107f backout the switch to use a zone for vlan tags; this requires
vlans be present if any driver with h/w vlan tagging is configured

28f4067fe0 - In vlan_input(), always mask off all but the VLID bits from tags
extracted from received frames, both in the IFCAP_VLAN_HWTAGGING case
  and not. (Some drivers may already do this masking internally, but
  doing it here doesn't hurt and insures consistency.)

- In vlan_ioctl(), don't let the user set a VLAN ID value with anything
  besides the VLID bits set, otherwise we will have trouble matching
  an interface in vlan_input() later.

bf8e8a6e8f Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.
Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

5852b81f42 o eliminate separate callback interface for h/w tagged input packets; instead
drivers "tag packets" with an m_tag and the input packet handling recognizes
  such packets and does the right thing
o track the number of active vlans on an interface; this lets lots of places
  only do vlan-specific processing when needed
o track changes to ether_ifdetach/ether_ifattach
o track bpf changes
o eliminate the use of M_PROTO1 for communicating to drivers about tagged
  packets
o eliminate the use of IFF_LINK0 for drivers communicating to the vlan code
  that they support h/w tagging; replaced by explicit interface capabilities
o add ifnet capabilities for h/w tagging and support of "large mtu's"
o use new interface capabilities to auto-configure use of large mtu's and h/w
  tagging
o add support for proper handling of promiscuous mode
o document driver/vlan communication conventions

9a5e4c88a3 Simplify the interface cloning framework by handling unit
unit allocation with a bitmap in the generic layer.  This
allows us to get rid of the duplicated rman code in every
clonable interface.

adae17d5bf Change the type of the VLAN interface from IFT_PROPVIRTUAL,
which was a temporary hack, to IFT_L2VLAN, which is the type
assigned by IANA.

15b9bcb121 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

ce079123e3 The current code incorrectly assumes that all vlans
are configured, and/or associated with a parent device.  If you
receive a frame for a VLAN that's not in the list, you walk off
the end of the list.  Boom.

ec566039ab Add preliminary support for IEEE 802.1Q VLAN tagging. It doesn't actually
work reliably yet (I've had panics), but it does seem to occasionally
be able to transmit and receive syntactically-correct packets.
Also fixes one of if_ethersubr.c's legion style bugs, and removes
the hostcache code from standard kernels---the code that depends on it
is not going to happen any time soon, I'm afraid.
