patch 'examples/ipsec-secgw: fix IV length in CTR 192/256' has been queued to stable release 24.11.2

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/12/25. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/c0be494e48b95495ba1976d61d71df60f0e1849e

Thanks.

Kevin

Subject: [PATCH] examples/ipsec-secgw: fix IV length in CTR 192/256

[ 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")
