From 6fb8045319ef172dc88a8142e7f8b58c7608137e Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:50 -0400 Subject: net: ieee802154: forbid monitor for del llsec devkey This patch forbids to del llsec devkey for monitor interfaces which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
