Documentation said that vm need to be restart after enable/disable
firewall option on interface.
This is wrong, the fwbr is added/removed online, and tap are
unplug/plug to fwbr online too
can selectively enable the firewall for each interface. This is
required in addition to the general firewall `enable` option.
-The firewall requires a special network device setup, so you need to
-restart the VM/container after enabling the firewall on a network
-interface.
