From 30a391a13ab9215d7569da4e1773c5bb4deed96d Mon Sep 17 00:00:00 2001 From: Roman Mashak Date: Wed, 16 Nov 2016 17:16:10 -0500 Subject: net sched filters: pass netlink message flags in event notification Userland client should be able to read an event, and reflect it back to the kernel, therefore it needs to extract complete set of netlink flags. For example, this will allow "tc monitor" to distinguish Add and Replace operations. Signed-off-by: Roman Mashak Signed-off-by: Jamal Hadi Salim Signed-off-by: David S.
