man 4 netgraph
man 4 ng_bridge
also a daemon-news article on how it works.

Rate limitting is one thing that isn't there yet. If we pulled our fingers out,
I guess we would have ripped the dummynet rate limmiter out of where it is
and placed it into a netgraph node where it would be generally useful
instead of being hardcoded into one (sometimes useful) localtion in the 
netoworking stacks.

there is a rate limitter based on netgraph available from:

but I have not tried it.

I need to look at it again as I believe it has improved and 
may be generally useful.
When I looked at it last it was a bit alpha.
It probably needs rewriting for the new netgraph API in -current.
