From 3bcc0cec818fa969fe555b44443347211ed787a3 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Fri, 4 Aug 2017 14:28:58 +0200 Subject: [PATCH] net: sched: change names of action number helpers to be aligned with the rest The rest of the helpers are named tcf_exts_*, so change the name of the action number helpers to be aligned. While at it, change to inline functions. Signed-off-by: Jiri Pirko Acked-by: Jamal Hadi Salim Signed-off-by: David S.
