From 4c9b4f55ad1f5a4b6206ac4ea58f273126d21925 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:51 -0400 Subject: [PATCH] net: ieee802154: stop dump llsec seclevels for monitors This patch stops dumping llsec seclevels for monitors which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
