Description Rebecca Cran freebsd_committer freebsd_triage 2009-12-10 18:00:14 UTC 
if_bridge(4) says that a bridge works like a hub, but a hub is a device which blindly forwards every packet it receives to every connected port.  A switch learns which MAC addresses are on which ports and only forwards packets on the appropriate ports.

Fix: Patch attached with submission follows:
How-To-Repeat: man if_bridge
