Fix some typos in the comment as well.
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.

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

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.
