patch 'net/mlx5: fix wait descriptor opcode for ConnectX-7' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=a04fa37e6e4756cc9f8c22ed1517c979b92a1c2f

Thanks.

Subject: [PATCH] net/mlx5: fix wait descriptor opcode for ConnectX-7
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 2c7cb21a42fa64d68c0bc026f89f1ce561764da2 ]

Since ConnectX-7 the special hardware capability to schedule
packet sending on specified time is provided. It uses special
WAIT WQE (hardware descriptor) with wait condition defined
by opcode. The CYCLIC_BIGGER was wrongly used instead of
CYCLIC_SMALLER. This caused arbitrary and stale time shift
in traffic scheduling.

Fixes: 49e8797619e40 ("net/mlx5: support wait on time in Tx")
