Don't know how currently - we need to look. The only possibility how to put lora in _softmac_ 802.15.4 is for me to introduce new "lora_register_hw" function who registered a special "lora" interface type (like node in 802.15.4) and use some of ieee802154 infrastructure and of course a lora.c which do some frame parsing on upper layer... Upper layers need to be some "net/lora" then... Just an idea how I can imagine how it _could_ work... to put lora in SoftMAC here. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
