From 07714229e0e2e9ad8ea19582ad3c41578ccb8c4c Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:48 -0400 Subject: net: ieee802154: stop dump llsec devkeys for monitors [ Upstream commit 080d1a57a94d93e70f84b7a360baa351388c574f ] 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.
