Subject: [net 03/18] net/mlx5e: TC, Reject rules with drop and modify hdr action
Date: Tue, 1 Feb 2022 21:03:49 -0800 [thread overview]
Message-ID: <20220202050404.100122-4-saeed@kernel.org> (raw)
In-Reply-To: <20220202050404.100122-1-saeed@kernel.org>
From: Roi Dayan <roid@nvidia.com>
This kind of action is not supported by firmware and generates a
syndrome.
kernel: mlx5_core 0000:08:00.0: mlx5_cmd_check:777:(pid 102063): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x8708c3)
Fixes: d7e75a325cb2 ("net/mlx5e: Add offloading of E-Switch TC pedit (header re-write) actions")
