patch 'net/vmxnet3: support larger MTU with version 6' has been queued to stable release 23.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=5bab0b75fb373232aab6a4146bff851353bd96c3

Thanks.

[ 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")
