From abbb0d33632ce931ca9c814813ee131351f6b92f Mon Sep 17 00:00:00 2001 From: Vlad Buslov Date: Wed, 30 Oct 2019 16:09:05 +0200 Subject: net: sched: extend TCA_ACT space with TCA_ACT_FLAGS Extend TCA_ACT space with nla_bitfield32 flags. Add TCA_ACT_FLAGS_NO_PERCPU_STATS as the only allowed flag. Parse the flags in tcf_action_init_1() and pass resulting value as additional argument to a_o->init().
