From 01634047bf0d5c2d9b7d8095bb4de1663dbeedeb Mon Sep 17 00:00:00 2001 From: "kaixi.fan" Date: Wed, 18 Aug 2021 10:22:15 +0800 Subject: ovs: clear skb->tstamp in forwarding path fq qdisc requires tstamp to be cleared in the forwarding path. Now ovs doesn't clear skb->tstamp. We encountered a problem with linux version 5.4.56 and ovs version 2.14.1, and packets failed to dequeue from qdisc when fq qdisc was attached to ovs port.
