Yes, the patch is purely to add the autobridge feature. Its controlled
from rc.conf and a typical setup would be:

# create the bridge and add the wired interface
cloned_interfaces="bridge0"
ifconfig_bridge0="up addm fxp0"

# set it so that tap interfaces get added too
autobridge_interfaces="bridge0"
autobridge_bridge0="tap*"

Well it does that too while not the intention of the patch. Think of it
as a bonus.
