Subject: [patch net-next v2 03/20] net: sched: change names of action number helpers to be aligned with the rest
From: Jiri Pirko <jiri@...lanox.com>
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.
