/etc/rc.conf is parsed as a shellscript, so later definitions of
variables (such as ifconfig_bridge0) overwrite earlier definitions.
Either combine the two ifconfig_bridge0 definitions into a single
stanza, or change the first from ifconfig_bridge0= to
create_args_bridge0= . The network setup rcscript provides create_args_*
to set parameters that can only be set during interface creation (like
name), but it also happens to work well for setting physical parameters
of synthetic interfaces, such as the devices slaved to a bridge.
