patch 'net/hns3: fix mailbox wait time' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/9c10b251a11f4842109a1bb59ad08bd78d89831c

Thanks.

Kevin

Subject: [PATCH] net/hns3: fix mailbox wait time

[ upstream commit 5a2b22b40f3052a8898194fd8c235440ad1d85d8 ]

The mailbox wait time can be specified at runtime. But the variable that
controls this time are not initialized when the variable isn't designated
or is specified as an invalid value, which will fail to initialize device
in the case where no device is bound to initialize the device.

Fixes: 2fc3e696a7f1 ("net/hns3: add runtime config for mailbox limit time")
