From e8cb5bcf6ed6d42227c453a3a3170105462f69df Mon Sep 17 00:00:00 2001 From: Baowen Zheng Date: Fri, 17 Dec 2021 19:16:26 +0100 Subject: net: sched: save full flags for tc action Save full action flags and return user flags when return flags to user space. Save full action flags to distinguish if the action is created independent from classifier. We made this change mainly for further patch to reoffload tc actions.
