    Subject[PATCH 4.9 10/37] net: ieee802154: stop dump llsec devs for monitors
    Date
    From: Alexander Aring <aahringo@redhat.com>

    [ Upstream commit 5582d641e6740839c9b83efd1fbf9bcd00b6f5fc ]

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