From 589dad6d71a72dd7912e5070c63f6bf1f561b5cf Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 15 Feb 2018 10:54:56 -0500 Subject: [PATCH] net: sched: act: add extack to init callback This patch adds extack support for act init callback api. This prepares to handle extack support inside each specific act implementation. Based on work by David Ahern Cc: David Ahern Signed-off-by: Alexander Aring Signed-off-by: David S.
