| Subject: net: ieee802154: stop dump llsec devkeys for monitors |
| |
| From: Alexander Aring <aahringo@redhat.com> |
| |
| [ Upstream commit 080d1a57a94d93e70f84b7a360baa351388c574f ] |
| |
| This patch stops dumping llsec devkeys for monitors which we don't support |
| yet. Otherwise we will access llsec mib which isn't initialized for |
| monitors. |
