Subject: [PATCH 23.11 1/3] net/mlx5/hws: fix port ID for root table
Date: Mon, 22 Apr 2024 18:50:14 +0200	[thread overview]
Message-ID: <20240422165016.197542-2-dsosnowski@nvidia.com> (raw)
In-Reply-To: <20240422165016.197542-1-dsosnowski@nvidia.com>

From: Erez Shitrit <erezsh@nvidia.com>

[ upstream commit 572fe9ef2f461b7e7e195a3a4da5bf0c11f35949 ]

In root tables matcher and rule need to have their port-id, otherwise
the translate function that done in dpdk layer will not get the right
attributes.
For that whenever the matcher is matching the source-port we need to get
the relevant port-id before calling the translate function.

Fixes: 405242c52dd5 ("net/mlx5/hws: add rule object")
