22dcc3c17b Add the vlan tag to the bridge route table. This allows a vlan trunk to be 
bridged, previously legitimate traffic was not passed as the bridge could not
tell that it was on a different Ethernet segment.

All non-tagged traffic is treated as vlan1 as per IEEE 802.1Q-2003

787096051b These days P2P means peer-2-peer (also well known from serveral filesharing 
protocols) while PointToPoint has been PtP links. Change the variables
accordingly while the code is still fresh and undocumented.

6c32e05ca3 Sync with the OpenBSD port of RSTP 
- use flags rather than sperate ioctls for edge, p2p
 - implement p2p and autop2p flags
 - define large pathcost constant as ULL
 - show bridgeid and rootid in ifconfig

3df7fad0cf Add a new address cache type called sticky. On an interface marked sticky any 
address learned by the bridge is made permanent, the address will not age out
and most importantly will not migrate to another interface.

This can be used to stop mac address poisoning or clients roaming in much the
same way as static entries without the hassle of preloading the table.

3fab76690c Bring in support for the Rapid Spanning Tree Protocol (802.1w). 
RSTP provides faster spanning tree convergence, the protocol will exchange
information with neighboring switches to quickly transition to forwarding
without creating loops. The code will default to RSTP mode but will downgrade
any port connected to a legacy STP network so is fully backward compatible.

from another interface/machine/network.

31997bf223 Add if_bridge, which provides more advanced Ethernet bridging and 802.1d 
spanning tree support.

Based on Jason Wright's bridge driver from OpenBSD, and modified by Jason R.
Thorpe in NetBSD.
