patch 'examples/ipsec-secgw: fix crash in event vector mode' has been queued to stable release 23.11.5

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/10/25. 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=905ff393d18b024b7663cec7cfde74f28200b59d

Thanks.

Subject: [PATCH] examples/ipsec-secgw: fix crash in event vector mode
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 811383ef109d8dae04c0681b84de09c51f153543 ]

Launching ipsec-secgw application in event vector mode
after traffic has started results in segfault because
we are receiving few IPSec packet and application is trying
to decrypt IPsec packets using lookaside protocol.
This contradicts inline event mode.This patch fixes the same
by freeing IPsec packets and processing only plain packets.

Fixes: 1d5078c6cf19 ("examples/ipsec-secgw: support event vector in lookaside mode")
