patch 'net/failsafe: fix secondary process probe' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/30/21. 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/db9d14af1c2572ace1ec790052533fcc6b100f14

Thanks.

Subject: [PATCH] net/failsafe: fix secondary process probe
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 47f5dee19e5f9a2cf1883a7119675d7a25470aca ]

Remove the vdev args check for secondary process which prevents the
secondary from attaching to the device created by the primary process
via the hotplug framework. This check was removed for other vdevs but
was missed for failsafe.

Fixes: 4852aa8f6e21 ("drivers/net: enable hotplug on secondary process")
