[dpdk-stable] patch 'net/bonding: fix link speed update in broadcast mode' has been queued to LTS release 17.11.10

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to LTS release 17.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/21/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Thanks.

Luca Boccassi

Subject: [PATCH] net/bonding: fix link speed update in broadcast mode

[ upstream commit db3216e76609647ce8dc256d478c8cc7095a23d4 ]

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")
