From d49c5174510f80d57c5e8fca478a7b382158f5e4 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:45 -0400 Subject: [PATCH] net: ieee802154: stop dump llsec devs for monitors [ Upstream commit 5582d641e6740839c9b83efd1fbf9bcd00b6f5fc ] This patch stops dumping llsec devs for monitors which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
