So far there were two monitor frame formats: 1) 802.11 frames (with frame (sub)type & all addresses) 2) 802.11 frames with the radiotap header Testing the latest FullMAC firmwares for 4366b1/4366c0 resulted in discovering a new format being used. It seems (almost?) identical to the one known from ucode used in SoftMAC devices which is most likely the same codebase anyway. While new firmwares will /announce/ radiotap header support using the "rtap" fw capability string it seems no string was added for the new ucode header format. All above means that: 1) We need new format support when dealing with a received frame 2) A new feature bit & mapping quirks have to be added manually As for now only an empty radiotap is being created. Adding support for extracting some info (band, channel, signal, etc.) is planned for the future.
