From fb3c5cdf88cd504ef11d59e8d656f4bc896c6922 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:42 -0400 Subject: [PATCH] net: ieee802154: stop dump llsec keys for monitors This patch stops dumping llsec keys for monitors which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
