[PATCH 5.10 09/29] net/sched: fix miss init the mru in qdisc_skb_cb

[Greg Kroah-Hartman]

From: wenxu <we...@ucloud.cn>

[ Upstream commit aadaca9e7c392dbf877af8cefb156199f1a67bbe ]

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")
