Subject: [PATCH RESEND wpan 12/15] net: ieee802154: stop dump llsec seclevels for monitors
Date: Sun,  4 Apr 2021 20:30:51 -0400	[thread overview]
Message-ID: <20210405003054.256017-13-aahringo@redhat.com> (raw)
In-Reply-To: <20210405003054.256017-1-aahringo@redhat.com>

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.
