Subject: [net-next 10/15] net/mlx5e: TC, Use common function allocating flow mod hdr or encap mod hdr
Date: Wed, 18 Jan 2023 10:35:57 -0800	[thread overview]
Message-ID: <20230118183602.124323-11-saeed@kernel.org> (raw)
In-Reply-To: <20230118183602.124323-1-saeed@kernel.org>

From: Roi Dayan <roid@nvidia.com>

Use mlx5e_tc_attach_mod_hdr() when allocating encap mod hdr and
remove mlx5e_tc_add_flow_mod_hdr() which is not being used now.
