Recent kernels will forward link local frames as long as STP is disabled.
Older kernels will not.
The assumption is that if STP is enabled, then it will be managing
control plane.

bridge: relay bridge multicast pkgs if !STP
Currently the bridge catches all STP packets; even if STP is turned
off. This prevents other systems (which do have STP turned on)
from being able to detect loops in the network.
With this patch, if STP is off, then any packet sent to the STP
multicast group address is forwarded to all ports.
Based on earlier patch by Joakim Tjernlund with changes
to go through forwarding (not local chain), and optimization
that only last octet needs to be checked.
