Subject: [PATCH AUTOSEL 5.4 21/39] net: ieee802154: forbid monitor for add llsec key
From: Alexander Aring <aahringo@...hat.com>
[ Upstream commit 08470c5453339369bd3d590c4cbb0b5961cdcbb6 ]
This patch forbids to add llsec key for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
