patch 'event/dlb2: fix event weight handling in SSE code path' has been queued to stable release 24.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/12/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/b5906479c816db6926d0bc3ae615da292a379891

Thanks.

Kevin

Subject: [PATCH] event/dlb2: fix event weight handling in SSE code path

[ upstream commit 96357d5afefc7f4be8f5735f0d5ea011e68d24f2 ]

Commit 6e2e98d6775b ("event/dlb2: support independent enqueue") updated
the avx512 code path with support for the event, or "qe" weights.
However, the SSE code path looks to have been missed in the update.
Update the SSE "build_hcws" function to match the changes made to the
AVX-512 version.

Bugzilla ID: 1616
Fixes: 6e2e98d6775b ("event/dlb2: support independent enqueue")
