Fixed MAC learning issue when ovs offload enabled. OVS firewall reduce
the usage of normal actions to reduce cpu utilization. This causing flood
rule because there is no MAC learning on ingress traffic. While this ok
for none offload case, when using ovs offload flood rule is not
offloaded. This fix the MAC learning in the offload, so we avoid flood
rule.

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
