From 40f542931d7576a637787845cac64514254f9136 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:49 -0400 Subject: net: ieee802154: forbid monitor for add llsec devkey [ Upstream commit a347b3b394868fef15b16f143719df56184be81d ] This patch forbids to add llsec devkey for monitor interfaces which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
