Message-Id: <1471152902-12444-8-git-send-email-xiyou.wangcong@gmail.com> Date: Sat, 13 Aug 2016 22:35:02 -0700 From: Cong Wang <xiyou.wangcong@...il.com> To: netdev@...r.kernel.org Cc: jhs@...atatu.com, Cong Wang <xiyou.wangcong@...il.com>, Roman Mashak <mrv@...atatu.com> Subject: [Patch net v4 7/7] net_sched: allow flushing tc police actions From: Roman Mashak <mrv@...atatu.com> The act_police uses its own code to walk the action hashtable, which leads to that we could not flush standalone tc police actions, so just switch to tcf_generic_walker() like other actions. (Joint work from Roman and Cong.)
