From 4bb1b116b7f37a64c08d28213a2e6f87fcef2d8b Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 2 Nov 2017 15:07:01 +0100 Subject: [PATCH] net: sched: move block offload unbind after all chains are flushed Currently, the offload unbind is done before the chains are flushed. That causes driver to unregister block callback before it can get all the callback calls done during flush, leaving the offloaded tps inside the HW. So fix the order to prevent this situation and restore the original behaviour. Reported-by: Alexander Duyck Reported-by: Jakub Kicinski Signed-off-by: Jiri Pirko Signed-off-by: David S.
