From de4784ca030fed17d527dbb2bb4e21328b12de94 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Mon, 7 Aug 2017 10:15:32 +0200 Subject: [PATCH] net: sched: get rid of struct tc_to_netdev Get rid of struct tc_to_netdev which is now just unnecessary container and rather pass per-type structures down to drivers directly. Along with that, consolidate the naming of per-type structure variables in cls_*. Signed-off-by: Jiri Pirko Acked-by: Jamal Hadi Salim Signed-off-by: David S.
