patch 'examples/ipsec-secgw: fix SA salt endianness' has been queued to stable release 23.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/14/24. 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=427fa0723877511e4cb6c98f70ca5e3689aa5d02

Thanks.

[ upstream commit e6bfd9676109f904b4f263402e77105fdca8e67c ]

The SA salt of struct ipsec_sa is a CPU-endian u32 variable, but it’s
value is stored in an array of encryption or authentication keys
according to big-endian. So it maybe need to convert the endianness
order to ensure that the value assigned to the SA salt is CPU-endian.

Fixes: 50d75cae2a2c ("examples/ipsec-secgw: initialize SA salt")
Fixes: 9413c3901f31 ("examples/ipsec-secgw: support additional algorithms")
Fixes: 501e9c226adf ("examples/ipsec-secgw: add AEAD parameters")
