Hi, The motivation for this patch is to assist using a WiiU Gamepad with Linux. The WiiU Gamepad is an input device that also contains an LCD touchscreen, speakers and a variety of sensors. The Gamepad connects to an access point (usually the WiiU console itself, but it can be coerced to connect to a properly configured hostap). The Gamepad provides five services over UDP. Two of the services that are provided (audio and video streaming to the device) use the TSF as a timestamp in the application layer. The firmware on the Gamepad checks to make sure that incoming packets for these services have timestamps within 1000us of its own internal clock, which is synced to the TSF of the access point. At the moment, users who want to use this device have to manually apply a kernel patch similar to that which was first posted to this list a year ago. This patch is my attempt to implement the functionality using a more conventional API and make it easier for end users. Should I include protocol implementation details specific to this device in the documentation of the NL80211_CMD_GET_TSF command?
