From 6c8caf78304fe2117e16e0e5ee29267ec3b9b51f Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 4 Apr 2021 20:30:47 -0400 Subject: net: ieee802154: forbid monitor for del llsec dev [ Upstream commit ad8f9de1f3566686af35b1c6b43240726541da61 ] This patch forbids to del llsec dev for monitor interfaces which we don't support yet. Otherwise we will access llsec mib which isn't initialized for monitors.
