patch 'cryptodev: fix build without crypto callbacks' 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=578ee207209f1b321f12d59104fc9c273374ccee

Thanks.

Subject: [PATCH] cryptodev: fix build without crypto callbacks
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit cfa443351ef581b7189467842ca102ab710cb7d2 ]

Crypto callbacks APIs are available in header files but when
the macro RTE_CRYPTO_CALLBACKS unset, test application need to
put #ifdef in its code.

The test application should be able to build and run, regardless
DPDK library is built with RTE_CRYPTO_CALLBACKS defined or not.

Added ENOTSUP from the beginning of the APIs implementation
if RTE_CRYPTO_CALLBACKS macro is unset/undefined.

Fixes: 1c3ffb95595e ("cryptodev: add enqueue and dequeue callbacks")
Fixes: 5523a75af539 ("test/crypto: add case for enqueue/dequeue callbacks")
