[dpdk-stable] patch 'net/failsafe: report minimum and maximum MTU' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/7fe1e5cdb90fef782d2752ba1992edaf65fc49f4

Thanks.

[ upstream commit c0396a48b526eb3d38c941a7e7d63d360a789d16 ]

Take minimum and maximum MTU values for subdevices and
report maximum of minimums and minimum of maximums.
