Add policing to drop-log interfaces
Add policing to drop-log interfaces

To prevent excessive dropped packets from swamping the CPU,
add 1 Mbps policing to drop-log interface. Packet size can be 12Kb
at the most(MTU).But typically around 250Bytes. This allows for
around 500 pps for 250B packets or around 83 pps for 1500B.
Minor fix for issue caused by another commit.
