From e4f9e64b82b55f07c4f870f2571be60f1d0ca80b Mon Sep 17 00:00:00 2001 From: Baowen Zheng Date: Mon, 13 Dec 2021 15:46:04 +0100 Subject: [PATCH] flow_offload: return EOPNOTSUPP for the unsupported mpls action type We need to return EOPNOTSUPP for the unsupported mpls action type when setup the flow action. In the original implement, we will return 0 for the unsupported mpls action type, actually we do not setup it and the following actions to the flow action entry.
