patch 'event/cnxk: fix OOP handling in event mode' has been queued to stable release 23.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/30/24. 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=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=80a61a0a00e593bc6242a9e8f0a210936885c9b3

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 01a990fe40e827c5f3497f785ce7fd68bff8ef5c ]

Update event device with NIX_RX_REAS_F to handle
out of place processing for SKUs that does not
support reassembly as cn10k driver process OOP
with NIX_RX_REAS_F enabled.

Fixes: 5e9e008d0127 ("net/cnxk: support inline ingress out-of-place session")
