patch 'examples/ipsec-secgw: fix IV length in CTR 192/256' has been queued to stable release 23.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/10/25. 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=0ac73425a8b36b3de6dd5430dec8f9c1c284902a

Thanks.

Subject: [PATCH] examples/ipsec-secgw: fix IV length in CTR 192/256
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 7e2a7c336737084d8d8ef89260e511ff5670edbf ]

This patch fixes IV length to 8 in case of AES-CTR 192/256.
AES-CTR IV length is set 8 in SA config as it is
used for per packet IV length and set it to 16
in xform since the application populates 16B IV
in the datapath. AES-CTR requires 16B IV
constructed from nonce and counter.

Fixes: 9413c3901f31 ("examples/ipsec-secgw: support additional algorithms")
