Subject: Re: [PATCH openEuler-1.0-LTS 0/6] Fix the problem that the number of tcp timeout retransmissions is lost
hi zhenyuan:
针对你先前提交的“Fix the problem that the number of tcp timeout
retransmissions is lost”补丁集，我们在内部review的时候committer给了如下
检视意见
切换EDT主线有 tcp 和 fq 的几个patchset和bugfix, 这里建议先合入解决本问题
后边的3个patch。
因此是否只合后三个patch就可以满足能够解决你目前遇到的问题。
