From: Alexander Aring Date: Thu, 15 Feb 2018 15:54:57 +0000 (-0500) Subject: net: sched: act: add extack for lookup callback X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=331a9295de23;p=openwrt%2Fstaging%2Fblogic.git net: sched: act: add extack for lookup callback This patch adds extack support for act lookup callback api. This prepares to handle extack support inside each specific act implementation. Cc: David Ahern Signed-off-by: Alexander Aring Signed-off-by: David S.
