i am doing some minor fixes to the non-netgraph version of
the bridging code.

i'd rather do as much as possible in userspace, and issue appropriate
calls (basically sysctl or similar to enable/disable forwarding
on some of the bridged interfaces) when necessary.
If you need a specific control interface i will be glad to
implement it, and your spanningTreed will be much much easier
to implement, test, maintain and reuse for different bridging things
(not to mention that a single box can act as multiple independent
bridges for which you want multiple spanning trees).
let me know if you have some spanning tree code that you want to
test/integrate.
cheers
