batman-adv: ELP - send unicast ELP packets for throughput sampling
In case of an unused wireless link, the mac80211 throughput estimation won't get updated further. Consequently, the reported throughput metric will become obsolete. With this patch unicast sampling is introduced by periodically sending unicast ELP packets to each neighbor on idle WiFi links. These sampling packets will fill an entire frame, so that the measurement is as reliable as possible Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch>
