| * 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. |
