| Subject: net: ieee802154: forbid monitor for add llsec dev |
| |
| From: Alexander Aring <aahringo@redhat.com> |
| |
| [ Upstream commit 5303f956b05a2886ff42890908156afaec0f95ac ] |
| |
| This patch forbids to add llsec dev for monitor interfaces which we |
| don't support yet. Otherwise we will access llsec mib which isn't |
| initialized for monitors. |
