From f8fab3169464623b88d0f423f8de2b28809c2fcf Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 7 Apr 2022 10:35:30 +0300 Subject: [PATCH] net/sched: act_vlan: Add extack message for offload failure For better error reporting to user space, add an extack message when vlan action offload fails. Currently, the failure cannot be triggered, but add a message in case the action is extended in the future to support more than the current set of modes.
