| Subject: net: ieee802154: forbid monitor for del llsec dev |
| |
| From: Alexander Aring <aahringo@redhat.com> |
| |
| [ 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. |
