[PATCH wpan 14/17] net: ieee802154: stop dump llsec seclevels for monitors

From: Alexander Aring <aahringo@redhat.com>
Date: 2021-02-28 15:22:13
Subsystem: ieee 802.15.4 subsystem, networking [general], the rest · Maintainers: Alexander Aring, Stefan Schmidt, Miquel Raynal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

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