From 31727f7957f7bc45f48db1477630f5871fe3d14b Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:48 -0400 Subject: [PATCH] net: ieee802154: stop dump llsec devkeys for monitors This patch stops dumping llsec devkeys for monitors which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
