Subject: [PATCH AUTOSEL 4.4 14/23] net: ieee802154: forbid monitor for add llsec devkey
Date: Mon, 12 Apr 2021 12:27:27 -0400 [thread overview]
Message-ID: <20210412162736.316026-14-sashal@kernel.org> (raw)
In-Reply-To: <20210412162736.316026-1-sashal@kernel.org>
From: Alexander Aring <aahringo@redhat.com>
[ Upstream commit a347b3b394868fef15b16f143719df56184be81d ]
This patch forbids to add llsec devkey for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
