Subject[PATCH 4.4 09/32] net: ieee802154: stop dump llsec keys for monitors
Date
From: Alexander Aring <aahringo@redhat.com>

[ Upstream commit fb3c5cdf88cd504ef11d59e8d656f4bc896c6922 ]

This patch stops dumping llsec keys for monitors which we don't support
yet. Otherwise we will access llsec mib which isn't initialized for
monitors.
