patch 'net/vmxnet3: support larger MTU with version 6' has been queued to stable release 22.11.7

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/14/24. 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/74b7f4e42ca848fd599fc7826b2c00a9be92f398

Thanks.

Luca Boccassi

[ upstream commit a4b83a747d7d21c6d61b9ae69d39db5e1c700dcd ]

Virtual hardware version 6 supports larger max MTU, but the device
information (dev_info) did not reflect this, so it could not be used.

Fixes: b1584dd0affe ("net/vmxnet3: support version 6")
