From 7edf4d2baa8a19a829475c2fbe0a9f42c628385a Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:43 -0400 Subject: [PATCH] net: ieee802154: forbid monitor for add llsec key [ Upstream commit 08470c5453339369bd3d590c4cbb0b5961cdcbb6 ] This patch forbids to add llsec key for monitor interfaces which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
