From: Alexander Aring Date: Thu, 18 Jan 2018 16:20:53 +0000 (-0500) Subject: net: sched: cls: add extack support for delete callback X-Git-Tag: Ubuntu-5.2.0-15.16~5092^2~112^2~2 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=571acf2106963d6c1c0ce1ed13e711bd296b2d25;p=mirror_ubuntu-eoan-kernel.git net: sched: cls: add extack support for delete callback This patch adds extack support for classifier delete callback api. This prepares to handle extack support inside each specific classifier implementation. Cc: David Ahern Signed-off-by: Alexander Aring Acked-by: Jiri Pirko Signed-off-by: David S.
