Subject: [PATCH v9 net-next 1/3] net/sched: fix miss init the mru in qdisc_skb_cb
Date: Wed, 11 Nov 2020 17:19:30 +0800	[thread overview]
Message-ID: <1605086372-22822-2-git-send-email-wenxu@ucloud.cn> (raw)
In-Reply-To: <1605086372-22822-1-git-send-email-wenxu@ucloud.cn>

From: wenxu <wenxu@ucloud.cn>

The mru in the qdisc_skb_cb should be init as 0. Only defrag packets in the
act_ct will set the value.

Fixes: 038ebb1a713d ("net/sched: act_ct: fix miss set mru for ovs after defrag in act_ct")
