Subject: [dpdk-stable] [PATCH 01/18] net/bonding: fix link speed update in broadcast mode
Date: Tue, 10 Sep 2019 09:25:41 +0100
Message-ID: <1568103959-25572-2-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1568103959-25572-1-git-send-email-arybchenko@solarflare.com>

From: Igor Romanov <igor.romanov@oktetlabs.ru>

Fix the issue that the link speed of the bond device was set to the
link speed of the first active slave in broadcast mode.

Set the link speed of the bond device to the minimum value across
all of the slaves in that case.

Fixes: deba8a2f8b0b ("net/bonding: fix link properties management")
