From 45490ce2ff833c4ec0de66705e46ba41320860cb Mon Sep 17 00:00:00 2001 From: Baowen Zheng Date: Fri, 29 Jul 2022 11:16:41 +0200 Subject: [PATCH] nfp: flower: add support for tunnel offload without key ID Currently nfp driver will reject to offload tunnel key action without tunnel key ID which means tunnel ID is 0. But it is a normal case for tc flower since user can setup a tunnel with tunnel ID is 0. So we need to support this case to accept tunnel key action without tunnel key ID.
