[PATCH RESEND wpan 15/15] net: ieee802154: stop dump llsec params for monitors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch stops dumping llsec params for monitors which we don't support
yet. Otherwise we will access llsec mib which isn't initialized for
monitors.
