| Subject: net: ieee802154: forbid monitor for add llsec devkey |
| |
| 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. |
