[dpdk-stable] patch 'net/mlx5: fix comparison sign in flow engine' has been queued to stable release 20.11.1

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/8e9f688bdbd058b84c0501a5a12af52b1851516c

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: fix comparison sign in flow engine

[ upstream commit 16047bd015e292df2a6c61b8f4584f7c166d2f51 ]

The clang compiler warns on size mismatches of several
comparisons.

warning: comparison of integers of different signs

To resolve those the right types is used/cast to.

Fixes: 3e8edd0ef848 ("net/mlx5: update metadata register ID query")
Fixes: e554b672aa05 ("net/mlx5: support flow tag")
Fixes: c8f0abe7f89d ("net/mlx5: fix meter color register consideration")
