From 7b06e8aed283081010596c98a67f06c595affe51 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Wed, 9 Aug 2017 14:30:35 +0200 Subject: [PATCH] net: sched: remove cops->tcf_cl_offload cops->tcf_cl_offload is no longer needed, as the drivers check what they can and cannot offload using the classid identify helpers. So remove this. Signed-off-by: Jiri Pirko Signed-off-by: David S.
