I think Jason Thorpe was working on it the last time I checked.  From 
netbsd.org's news section:

Bridge support added to NetBSD-current (17 Aug) (top)
Jason Thorpe has committed support for building Ethernet bridges to 
NetBSD-current. Bridges are configured with a combination of ifconfig(8) 
and the new brconfig(8) utility. brconfig(8) can also be used to show a 
bridge's status, like so:

swinger:thorpej 1$ brconfig -a
bridge0: flags=41<UP,RUNNING>
         Configuration:
                 priority 32768 hellotime 2 fwddelay 15 maxage 20
         Interfaces:
                 fxp2 flags=3<LEARNING,DISCOVER>
                         port 4 priority 128
                 tlp0 flags=3<LEARNING,DISCOVER>
                         port 5 priority 128
         Address cache (max cache: 100, timeout: 1200):
                 00:20:6f:04:13:1d tlp0 1169 flags=0<>
                 08:00:2b:2b:a9:0e tlp0 914 flags=0<>
                 00:03:47:20:1b:7d fxp2 191 flags=0<>
                 00:00:f8:23:43:9d tlp0 148 flags=0<>
swinger:thorpej 2$
If you use the bridge code, please send Jason a mail and report on how 
well it works for you. If you have problems with it, please file a bug 
report with send-pr(1).

This support is based off Jason Wright's bridge driver for OpenBSD, with 
changes by Jason Thorpe.
