 Colo-compare gets packet from primary_in@var{chardevid} and secondary_in@var{chardevid}, than compare primary packet with
 secondary packet. If the packets are same, we will output primary
 packet to outdev@var{chardevid}, else we will notify colo-frame
 do checkpoint and send primary packet to outdev@var{chardevid}.
-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.
