From 8ec14402029d783720f4312ed8a925548e1dad61 Mon Sep 17 00:00:00 2001 From: Mao Zhongyi Date: Fri, 13 Oct 2017 14:32:07 +0800 Subject: colo-compare: compare the packet in a specified Connection A package from pri_indev or sec_indev only belongs to a particular Connection, so we only need to compare the package in the specified Connection's primary_list and secondary_list, rather than for each the whole Connection list to compare. This is time-consuming and unnecessary. Less checkpoint more efficiency.
