Colo-compare gets packet from address@hidden and address@hidden, than compare
primary packet with
secondary packet. If the packets are same, we will output primary
packet to address@hidden, else we will notify colo-frame
do checkpoint and send primary packet to address@hidden
-if it has the vnet_hdr_support flag, colo compare will send/recv packet with
vnet_hdr_len.
+In order to improve efficiency, we need to put the task of comparison

we must use it with the help of filter-mirror and filter-redirector.
