From 3b063ae57bdfec5e574ace440e6c3f34c4115a92 Mon Sep 17 00:00:00 2001 From: Amit Cohen Date: Thu, 7 Nov 2019 18:42:14 +0200 Subject: devlink: Add layer 3 generic packet exception traps Add layer 3 generic packet exception traps that can report trapped packets and documentation of the traps. Unlike drop traps, these exception traps also need to inject the packet to the kernel's receive path. For example, a packet that was trapped due to unreachable neighbour need to be injected into the kernel so that it will trigger an ARP request or a neighbour solicitation message.
