Subject: net: ieee802154: stop dump llsec devs for monitors
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5582d641e6740839c9b83efd1fbf9bcd00b6f5fc;p=linux.git

net: ieee802154: stop dump llsec devs for monitors

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.
