o on input don't strip the Ethernet header from packets
o input packet handling is now done with if_input
o track changes to ether_ifattach/ether_ifdetach API
o track changes to bpf tapping
o call ether_ioctl for default handling of ioctl's
o use constants from net/ethernet.h where possible

In order of importance:
+ each cluster now uses private data structures (filtering and
local address tables) so you can treat them as fully independent
switches. This part of the work was supported by:
Cisco Systems, Inc. - NSITE lab, RTP, NC.
+ cleaned up the handling of configuration, so the system will behave
much better when real or pseudo devices are dynamically attached
or detached. It should also not panic anymore on systems with large
number of devices, closing a few existings PRs on the topic.
+ while at it, add support for VLAN. This means that a FreeBSD box
can now work as a real VLAN switch, with trunk interfaces etc.
As an example:
ifconfig vlan0 vlan 3 vlandev dc0
ifconfig vlan1 vlan 4 vlandev dc0
net.link.ether.bridge_cfg="vlan0:3,dc1:3,vlan1:4,dc1:4"
uses dc0 as a trunk interface, and dc1 and dc3 as ports on vlans 3 and 4
You get the idea...
NOTA BENE: by default bridge_cfg is initialised to "" so even if
you enable bridging, no packets will be bridged until you set the
list of interfaces on which you want this to happen.
+ large restructuring of the code, moving private vars and types from
bridge.h to bridge.c.
+ added a lot of comments to the code to explain how to use it.

into stable (mostly , but not only, formatting and comments changes).

of the individual drivers and into the common routine ether_input().
Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.
The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.
The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.

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.
