patch 'net/intel: fix build with icx' has been queued to stable release 22.11.8

Hi,

FYI, your patch has been queued to stable release 22.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/19/25. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/07f9cfb97a534985bba679e80dc8d1297bf3357b

Thanks.

Luca Boccassi

Subject: [PATCH] net/intel: fix build with icx

[ upstream commit 2641704664267dd3ebe4ad77784ae28440dfaf60 ]

The Intel oneAPI DPC++/C++ Compiler (icx), issues warnings on build when
the "-march=native", or other configured global "-march" flag, is
overridden to "skylake-avx512", when compiling AVX-512 code.

Allow building with icx with warnings-as-errors flag (werror) enabled by
disabling the warning for the cases where we pass that extra "-march"
flag.

Fixes: e6a6a138919f ("net/i40e: add AVX512 vector path")
Fixes: 31737f2b66fb ("net/iavf: enable AVX512 for legacy Rx")
Fixes: 7f85d5ebcfe1 ("net/ice: add AVX512 vector path")
Fixes: 0fac6a1c44d5 ("common/idpf: add AVX512 for single queue model")
