From a442b761b24b6886f9a4e2ff5f8cb4824c96526b Mon Sep 17 00:00:00 2001 From: Ayala Beker Date: Tue, 20 Sep 2016 17:31:15 +0300 Subject: cfg80211: add add_nan_func / del_nan_func A NAN function can be either publish, subscribe or follow up. Make all the necessary verifications and just pass the request to the driver. Allow the user space application that starts NAN to forbid any other socket to add or remove functions.
