Subject: [PATCH AUTOSEL 5.11 40/51] net: ieee802154: forbid monitor for del llsec seclevel
Date: Mon, 12 Apr 2021 12:22:45 -0400	[thread overview]
Message-ID: <20210412162256.313524-40-sashal@kernel.org> (raw)
In-Reply-To: <20210412162256.313524-1-sashal@kernel.org>

From: Alexander Aring <aahringo@redhat.com>

[ Upstream commit 9dde130937e95b72adfae64ab21d6e7e707e2dac ]

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.
