| Subject: net: ieee802154: stop dump llsec keys for monitors |
| |
| From: Alexander Aring <aahringo@redhat.com> |
| |
| [ Upstream commit fb3c5cdf88cd504ef11d59e8d656f4bc896c6922 ] |
| |
| This patch stops dumping llsec keys for monitors which we don't support |
| yet. Otherwise we will access llsec mib which isn't initialized for |
| monitors. |
