From de7ecc45d9cd3da13c9d9b7816abb7d9713b531f Mon Sep 17 00:00:00 2001 From: Alaa Hleihel Date: Sun, 10 May 2020 15:04:32 -0400 Subject: [PATCH 108/312] [netdrv] net/mlx5: DR, Refactor VXLAN GPE flex parser tunnel code for SW steering Message-id: <20200510150452.10307-68-ahleihel@redhat.com> Patchwork-id: 306691 Patchwork-instance: patchwork O-Subject: [RHEL8.3 BZ 1789380 v2 67/87] net/mlx5: DR, Refactor VXLAN GPE flex parser tunnel code for SW steering Bugzilla: 1789380 RH-Acked-by: Kamal Heib RH-Acked-by: Jarod Wilson RH-Acked-by: Tony Camuso RH-Acked-by: Jonathan Toppins Bugzilla: http://bugzilla.redhat.com/1789380 Upstream: v5.5-rc1 commit 6e9e286e4ad53311b51b28fdc4b952ab7d2520c4 Author: Yevgeny Kliteynik Date: Mon Oct 28 16:30:27 2019 +0200 net/mlx5: DR, Refactor VXLAN GPE flex parser tunnel code for SW steering Refactor flex parser tunnel code: - Add definition for flex parser tunneling header for VXLAN-GPE - Use macros for VXLAN-GPE SW steering when building STE - Refactor the code to reflect that this is a VXLAN GPE only code and not a general flex parser code. This also significantly simplifies addition of more flex parser protocols, such as Geneve.
