o don't strip the Ethernet header from inbound packets; pass packets
up the stack intact (required significant changes to some drivers)
o reference common definitions in net/ethernet.h (e.g. ETHER_ALIGN)
o track ether_ifattach/ether_ifdetach API changes
o track bpf changes (use BPF_TAP and BPF_MTAP)

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

ether_header; instead drivers are to leave the Ethernet header at the
front of the packet
o add declarations for netgraph and vlan hooks that were removed from ethernet.h
o change various in-file calling conventions to track change in input API
o fixup bridge support to handle Ethernet header no longer being stripped
o add consistency checks to ether_input to catch problems with the change
in the API; some of these may want to be moved to #ifdef DIAGNOSTIC at a
later time (though they are not too expensive to leave as is)
o change ether_demux to eliminate the passing of the Ethernet header; it is
now expected at the front of the packet a la ether_input
o add ether_sprintf compatibility shim
o change ether_ifattach API to remove "bpf supported param" and add a pointer
to the MAC address to be installed for the LL address (this is for future
changes to divest struct arpcom from struct ifnet)

o Use 32-bit unsigned types for things that really are 32-bit quantities,
not bus_addr_t. These are not the same as a bus_addr_t, so don't use

the MAC policy list is busy during a load or unload attempt.
We assert no locks held during the cv wait, meaning we should
be fairly deadlock-safe. Because of the cv model and busy
count, it's possible for a cv waiter waiting for exclusive
access to the policy list to be starved by active and
long-lived access control/labeling events. For now, we
accept that as a necessary tradeoff.
