From 678eb199cc9df3bf1cb12fb2da22768b8d1b6bf3 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Fri, 29 May 2020 21:36:36 +0300 Subject: devlink: Create dedicated trap group for layer 3 exceptions Packets that hit exceptions during layer 3 forwarding must be trapped to the CPU for the control plane to function properly. Create a dedicated group for them, so that user space could choose to assign a different policer for them. Signed-off-by: Ido Schimmel Reviewed-by: Jiri Pirko Signed-off-by: David S.
