patch 'net/i40e: fix max frame size config at port level' has been queued to stable release 20.11.6

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/23/22. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/5b55b9b1ea723a2cebc8f51a44b3ae17055a0dd9

Thanks.

Subject: [PATCH] net/i40e: fix max frame size config at port level
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 2184f7cdeeaa7eb814e102fd01773db204ccd3bf ]

Previously, max frame size can only be set when link is up, and the wait
time is 1 sec. Startup time of 10G_BASET longer than 1s would result in
failure.

Actually, max frame size of media type I40E_MEDIA_TYPE_BASET can be set
regardless of link status.

This patch omitted the link status check of 10G_MEDIA_TYPE_BASET.

Fixes: a4ba77367923 ("net/i40e: enable maximum frame size at port level")
