From e88afe759a49f8d51d6cc5fc89d65b4a5768703f Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Sun, 9 Dec 2018 17:03:36 +0200 Subject: [PATCH] net/mlx5e: Err if asked to mirror a goto chain tc eswitch rule Currently we are not supporting this and not err-ing on that either. For now, just err if asked to do that.
