Subject: [PATCH wpan 16/17] net: ieee802154: forbid monitor for del llsec seclevel
Date: Sun, 28 Feb 2021 10:18:16 -0500	[thread overview]
Message-ID: <20210228151817.95700-17-aahringo@redhat.com> (raw)
In-Reply-To: <20210228151817.95700-1-aahringo@redhat.com>

This patch forbids to del llsec seclevel for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
