From c50bf2be7306cd37e4a8228acfe0fee36b9097dc Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Thu, 1 Oct 2020 18:11:46 +0300 Subject: devlink: add .trap_group_action_set() callback Add a new devlink callback, .trap_group_action_set(), which can be used by device drivers which do not support controlling the action (drop, trap) on each trap but rather on the entire group trap. If this new callback is populated, it will take precedence over the .trap_action_set() callback when the user requests a change of all the traps in a group.
