DOC: Frame transmission/registration support

Frame transmission and registration support exists to allow userspace entities such as wmediumd to receive and process all broadcasted frames from a mac80211_hwsim radio device.

This allow user space applications to decide if the frame should be dropped or not and implement a wireless medium simulator at user space.

Registration is done by sending a register message to the driver and will be automatically unregistered if the user application doesn't responds to sent frames. Once registered the user application has to take responsibility of broadcasting the frames to all listening mac80211_hwsim radio interfaces.

For more technical details, see the corresponding command descriptions below. enum hwsim_commands - supported hwsim commands

enum hwsim_tx_control_flags - flags to describe transmission info/status

These flags are used to give the wmediumd extra information in order to modify its behavior for each frame

: require TX status callback for this frame. : tell the wmediumd not to wait for an ack : Frame was acknowledged
