Subject: [PATCH v7 net-next 09/12] net: sched: save full flags for tc action
From: Baowen Zheng <baowen.zheng@...igine.com>
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.
