patch 'net/netvsc: increase VSP response timeout to 60 seconds' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/15/23. 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=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=64d7c1df889d7aaf68d519bc1f73c2c71f443694

Subject: [PATCH] net/netvsc: increase VSP response timeout to 60 seconds
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit d56475174855b1454cf004025b54d68e4a47f465 ]

The current timeout is set to 5 seconds. In Azure, tests show that it
may take up to 15 seconds for VSP to respond on busy nodes. The VSP
schedules unbounded work to process VSC request, there is no upper limit
on how long it takes to send response back to VSC.

In the NETVSC kernel mode driver, it waits forever for VSP response.
While in DPDK we can't wait forever, setting the timeout to 60 seconds.
