| Subject: ovs: clear skb->tstamp in forwarding path |
| |
| From: kaixi.fan <fankaixi.li@bytedance.com> |
| |
| [ Upstream commit 01634047bf0d5c2d9b7d8095bb4de1663dbeedeb ] |
| |
| 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. |
| |
| Fixes: fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC") |
