Subject: [PATCH AUTOSEL 5.4 30/39] net: ieee802154: forbid monitor for add llsec seclevel
Date: Mon, 12 Apr 2021 12:24:52 -0400 [thread overview]
Message-ID: <20210412162502.314854-30-sashal@kernel.org> (raw)
In-Reply-To: <20210412162502.314854-1-sashal@kernel.org>
From: Alexander Aring <aahringo@redhat.com>
[ Upstream commit 9ec87e322428d4734ac647d1a8e507434086993d ]
This patch forbids to add llsec seclevel for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
