patch 'net/bonding: fix MTU set for slaves' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/2c27da1e514f9a1b3d033880c8601639242253c5

Thanks.

Kevin

Subject: [PATCH] net/bonding: fix MTU set for slaves

[ upstream commit 20a53b1927da67f62366752ae2d737cb4ded9b6e ]

ethdev requires device to be configured before setting MTU.

In bonding PMD, while configuring slaves, bonding first sets MTU later
configures them, which causes failure if slaves are not configured in
advance.

Fixing by changing the order in slave configure as requested in ethdev
layer, configure first and set MTU later.

Bugzilla ID: 864
Fixes: b26bee10ee37 ("ethdev: forbid MTU set before device configure")
