From: Alexander Kozyrev <akozyrev@nvidia.com> To: dev@dpdk.org Cc: stable@dpdk.org, rasland@nvidia.com, viacheslavo@nvidia.com Subject: [dpdk-stable] [PATCH] net/mlx5: check extended metadata for meta modification Date: Wed, 7 Apr 2021 01:13:57 +0000 Message-ID: <20210407011357.22496-1-akozyrev@nvidia.com> (raw) The MODIFY_FIELD RTE action requires the extended metadata support in order to manipulate on METADATA register as well as on MARK register. Check if it is supported and reject the MODIFY_FIELD action if it is not just like it was done before for the MARK register modifications.
