Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/22/26. 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/7e3843c6e69737c1562bc1f00bb16f261bc3227d

Thanks.

Luca Boccassi

Subject: [PATCH] net: fix variable shadowing

[ upstream commit a2472f3a81d04c1cd5e08a0eb5dff87fba736935 ]

The "mask" local variable shadowed a global definition. The local var
was only used on two lines as a temporary value to pass the return value
of one function as a parameter to another. Therefore, we can remove the
shadowing issue by removing the variable.

Fixes: 17a937baed3e ("net: add CRC AVX512 implementation")
