Support AD-HOC mode
In this update, an ad-hoc (IBSS) mode has been added. Users can switch their device to IBSS mode using the following command : "iw dev [interface] set type ibss" To join a specific IBSS cell and configure other settings, users can use the command : "iw dev [interface] ibss join [SSID] [freq in MHz] [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz] [fixed-freq] [<fixed bssid>] [beacon-interval <TU>] [basic-rates <rate in Mbps,rate2,…>] [mcast-rate <rate in Mbps>] [key d:0:abcde]" eg. "iw dev vw3 ibss join Elian 2412 NOHT fixed-freq 00:76:77:33:00:00 beacon-interval 200" The command signifies that the device vw3 will either join an existing Ad-Hoc network named Elian or create one if it doesn't exist. The device will use the 2412 MHz frequency, not utilize High Throughput mode (802.11n), and maintain a fixed frequency without changes due to other devices. The BSSID (Basic Service Set Identifier) for the IBSS will be set as 00:76:77:33:00:00, and the beacon interval, which is the time between two consecutive beacons, will be set to 200 Time Units (TUs). To leave the current Ad-Hoc network, users can use command : "iw dev [interface] ibss leave" Additionally, ad-hoc related test items have been added, and the IBSS devices are scannable.
