Subject: [PATCH RESEND wpan 15/15] net: ieee802154: stop dump llsec params for monitors
Date: Sun,  4 Apr 2021 20:30:54 -0400
Message-ID: <20210405003054.256017-16-aahringo@redhat.com> (raw)
In-Reply-To: <20210405003054.256017-1-aahringo@redhat.com>

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