[dpdk-stable] patch 'net/virtio: report maximum MTU in device info' has been queued to stable release 20.11.3

Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/05/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/47d67fb4bbf1a7361438cf55d7465f57ca86924c

Thanks.

Luca Boccassi

Subject: [PATCH] net/virtio: report maximum MTU in device info

[ upstream commit 11d7bc9ff074dc5e37dd9ab51bb365669d08c3d6 ]

Fix the driver to report maximum MTU obtained from config if
VIRTIO_NET_F_MTU is supported or calculated based on maximum
Rx packet length.

Fixes: ad97ceece12c ("ethdev: add min/max MTU to device info")
