Aaron Huang 04ed6a3592 apf: Drop ARP reply if SPA is 0.0.0.0 ...

Some network re-writing packet from broadcast MACs to unicast,
result in this kind of packets cannot be dropped by APF filter.
Thus, drop ARP reply if source IP is 0.0.0.0.

Note: Linux kernel always ignores such replies in the function arp_process().
