| Subject: net: ieee802154: stop dump llsec devs for monitors |
| |
| From: Alexander Aring <aahringo@redhat.com> |
| |
| [ Upstream commit 5582d641e6740839c9b83efd1fbf9bcd00b6f5fc ] |
| |
| This patch stops dumping llsec devs for monitors which we don't support |
| yet. Otherwise we will access llsec mib which isn't initialized for |
| monitors. |
