* Handle both primiary and secondary network traffic on FXP phy port0

Redhat wanted to use single physical port to handle both their primary
and secondary network traffic.
1) handle ARP/Broadcast packets using FXP mirroring to primary interface
   VSI(D5) while the original packets are sent to P0's VSI(D4).
2) Unicast packets are selectively forwarded to the primary network
   interface based on DMAC lookup.

NOTE: Default behavior will be defined using devmem to reroute all the
phy0 traffic to D5's VSI. Once the VSP comes in, it will program the
above mentioned mirroring and dmac lookup P4 rules to take precedence
over the devmem defined default behavior.
