[PATCH wpan 13/17] net: ieee802154: forbid monitor for del llsec devkey

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

 



This patch forbids to del llsec devkey for monitor interfaces which we
don't support yet. Otherwise we will access llsec mib which isn't
initialized for monitors.
