Reading the MAC frame format I see not much in common with IEEE 802.15.4. Maybe they really refer to the link layer security parts only. Given that your driver operates in LoRa and thus will not work with any other 802.15.4 device I would not apply it to the ieee802154 subsystem. The driver is a good start for real LoRa support in the Linux kernel thought. I would very much welcome such support and would also be happy to help. (Not before November though as my next weeks will be to busy) Xue (in CC now) also has an interest in LoRa support in the Linux Kernel and already started some work if I remember correctly. If you both are interested to actively contribute to such a subsystem I would be happy to help getting it into the mainline kernel. Please let me both know what you think. I can ask for a linux-lora (or linux-lpwan?) list on vger to get the ball rolling for initial discussions. regards Stefan Schmidt
