patch 'efd: fix AVX2 support' has been queued to stable release 23.11.6

[Shani Peretz]

Hi,

FYI, your patch has been queued to stable release 23.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/26/25. 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/shanipr/dpdk-stable

This queued commit can be viewed at:
https://github.com/shanipr/dpdk-stable/commit/08c3dc2d9f15f063d1544b081d3639d002018744

Thanks.

Shani

Subject: [PATCH] efd: fix AVX2 support

[ upstream commit c367b9a07c55025eabe1dd6903f4b0f5c4c5d362 ]

When switching to Meson build, the compilation check on CC_SUPPORT_AVX2
became obsolete, thus the case EFD_LOOKUP_AVX2 became dead.
The function efd_lookup_internal_avx2() was never called,
and its header include rte_efd_x86.h has been removed later.

EFD_LOOKUP_AVX2 is chosen at runtime after checking AVX2 availability,
so the obsolete build-time check for AVX2 can be simply removed,
and the missing include added back.

Fixes: 5b9656b157d3 ("lib: build with meson")
Fixes: 30a1de105a5f ("lib: remove unneeded header includes")
