Does NetBSD (release or current) support transparent bridging?

I've seen some traffic on the OpenBSD misc list on how
OpenBSD has support for bridging.  I have a Sparc IPX running
NetBSD right now, and I would really like to bridge two ethernet
segments (a class C fractured over two disjoint segments), and
as always, I would prefer to do it with NetBSD.
