Subject: [PATCH wpan 05/17] net: ieee802154: stop dump llsec keys for monitors
Date: Sun, 28 Feb 2021 10:18:05 -0500
Message-ID: <20210228151817.95700-6-aahringo@redhat.com> (raw)
In-Reply-To: <20210228151817.95700-1-aahringo@redhat.com>

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.
