I didn't think to check the source file before, although I did skim the 
man page before my first mail at least :)  I didn't see anything useful 
in the man page or source code and I don't think the problem is tap 
specific.  I think its more of a general network issue possibly 
something to do with the fact that bridge(4) does not support 802.1d but 
I really don't know :P  I put more configuration information in my reply 
to Isaac Levy's post.

Thanks,
