[Xueming Li <xuemingl@nvidia.com>]

Hi,

FYI, your patch has been queued to stable release 23.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
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=69dc0d8ed261b364449f78cb1ad2e727e0c3fc10

Thanks.

Subject: [PATCH] examples/l3fwd: fix socket ID check
Cc: Xueming Li <xuemingl@nvidia.com>

[ upstream commit a7216f081767c7259dd3fba5eda0ca7b0bcb4595 ]

The expression:

  if ((socketid = rte_lcore_to_socket_id(lcore) != 0) &&

gets evaluated as socketid = (rte_lcore_to_socket_id(lcore) != 0)
which is not what was intended. This is goes all the way back
to first release.

Fixes: af75078fece3 ("first public release")
