From e505ac7f91b59e1165c143f14b208885658d2f94 Mon Sep 17 00:00:00 2001 From: Suanming Mou Date: Wed, 19 Feb 2020 16:26:19 +0200 Subject: [PATCH] net/mlx5: fix layer validation with decapsulation Currently, the flow validate function only validate the outermost layer with the header modify actions. If there is decapsulation action before the header modify action, the validation should choose the inner layer for validation. Add decapsulation check when validate with the header modify actions. Choose the inner layer once there is decapsulation action.
