Fixed a MAC learning issue when OVS offload is enabled. The OVS firewall
reduces the usage of normal actions to reduce CPU utilization. This
causes insertion of a flood rule because there is no MAC learning on
ingress traffic. While this is okay for the non-offload case, when using
OVS offload the flood rule is not being offloaded. This fixes the MAC
learning in the offload case, so we avoid the flood rule. For more
information, see bug
