It will be pushed if I get no objections before 07/25/23. 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://github.com/kevintraynor/dpdk-stable This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable/commit/baff3174c643cc2e27a799ba2b7c76d20c9df7c3 Thanks. Kevin --- >From baff3174c643cc2e27a799ba2b7c76d20c9df7c3 Mon Sep 17 00:00:00 2001 From: Rongwei Liu Date: Tue, 16 May 2023 08:43:29 +0300 Subject: [PATCH] net/mlx5: fix duplicated tag index matching in SWS [ upstream commit d5a7699c10651cb1cea2b18f94099e984c466b75 ] Duplicated matching tag index is not allowed in SWS because they are using the same matching field in the underlayer layout. For example: "tag index is 0 data spec 0x12 mask 0xff / tag index is 0 data spec 0x1234 mask 0xffff" is paradoxical matching condition and "tag index is 0 data spec 0x12 mask 0xff / tag index is 0 data spec 0x3400 mask 0xff00" should be "tag index is 0 data spec 0x3412 mask 0xffff" Add checking logic against it.
