patch 'baseband/acc100: fix clearing PF IR outside handler' has been queued to stable release 21.11.3

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/14/22. 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/9d91b3709d5752a6953e1165362e5a466b792512

Thanks.

Kevin

Subject: [PATCH] baseband/acc100: fix clearing PF IR outside handler

[ upstream commit 935745f56b9bf37ebece351170b47d3e6c215bc9 ]

Clearing of PF info ring outside of handler may cause interrupt to be
missed.
A condition in the ACC100 PMD implementation may cause an interrupt
functional handler call to be missed due to related bit being cleared
when checking PF info ring status.

Fixes: 06531464151 ("baseband/acc100: support interrupt")
