Subject: [v2 net 13/19] net/mlx5e: TC, Reject rules with forward and drop actions
Date: Wed, 23 Feb 2022 16:11:17 -0800 [thread overview]
Message-ID: <20220224001123.365265-14-saeed@kernel.org> (raw)
In-Reply-To: <20220224001123.365265-1-saeed@kernel.org>
From: Roi Dayan <roid@nvidia.com>
Such rules are redundant but allowed and passed to the driver.
The driver does not support offloading such rules so return an error.
Fixes: 03a9d11e6eeb ("net/mlx5e: Add TC drop and mirred/redirect action parsing for SRIOV offloads")
