Subject: [PATCH 14/14] net: clear skb->tstamp in bridge forwarding path

From: Paolo Abeni <[email-masked]>
Date: Tue, 8 Jan 2019 18:45:05 +0100

[ Upstream commit 41d1c8839e5f8cb781cc635f12791decee8271b7 ]

Matteo reported forwarding issues inside the linux bridge,
if the enslaved interfaces use the fq qdisc.

Similar to commit 8203e2d844d3 ("net: clear skb->tstamp in
forwarding paths"), we need to clear the tstamp field in
the bridge forwarding path.

Fixes: 80b14dee2bea ("net: Add a new socket option for a future transmit time.")
Fixes: fb420d5d91c1 ("tcp/fq: move back to CLOCK_MONOTONIC")
