Message-Id: <20230525034847.99268-2-saeed@kernel.org> Date: Wed, 24 May 2023 20:48:31 -0700 From: Saeed Mahameed <saeed@...nel.org> To: "David S. Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com>, Eric Dumazet <edumazet@...gle.com> Cc: Saeed Mahameed <saeedm@...dia.com>, netdev@...r.kernel.org, Tariq Toukan <tariqt@...dia.com>, Chris Mi <cmi@...dia.com> Subject: [net 01/17] net/mlx5e: Extract remaining tunnel encap code to dedicated file From: Chris Mi <cmi@...dia.com> Move set_encap_dests() and clean_encap_dests() to the tunnel encap dedicated file. And rename them to mlx5e_tc_tun_encap_dests_set() and mlx5e_tc_tun_encap_dests_unset(). No functional change in this patch. It is needed in the next patch.
