Subject: [PATCH 4.14 12/49] net: ieee802154: forbid monitor for add llsec dev
From: Alexander Aring <aahringo@...hat.com>
[ Upstream commit 5303f956b05a2886ff42890908156afaec0f95ac ]
This patch forbids to add llsec dev for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
