It will be pushed if I get no objections before 03/21/22. 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/52b3a9ca6dfdca45075d11d521eb7ce08ab3732a Thanks. Kevin --- >From 52b3a9ca6dfdca45075d11d521eb7ce08ab3732a Mon Sep 17 00:00:00 2001 From: Jiawei Wang Date: Wed, 9 Mar 2022 12:19:46 +0200 Subject: [PATCH] net/mlx5: fix sample flow action on trusted device [ upstream commit 9a726360dd3010a4c664e37682826b68a0a7f7fe ] A flow rule with sample action will be split into two sub flows, and a tag action was added implicitly in the sample prefix sub flow, the reserved metadata regC index was used for this tag action. The reserved metadata regC was shared with metering action, for ConnectX-5 trusted device (VF/SF), the reserved metadata regC was invalid since PF only supported the legacy metering. This patch adds the checking for the tag index and back to use the application tag if a failure happened.
