LoRaWAN defined by LoRa Alliance(TM) is the MAC layer over LoRa PHY. This part is soft-MAC as Andreas mentioned http://lists.infradead.org/pipermail/linux-lpwan/2018-December/000010.html > Also, you don't really have any user of this API in the set.

The soft-MAC is suitable for the LoRa chips' device drivers, like sx1276/77/78/79, RFM95/96/97/98W ... Still waiting for Andreas' sx1276 version 2 patch and more discussion. For example, how to make PF_LORA and PF_LORAWAN like Ethernet, PF_INET and PF_INET6 don't need separate devices either, both use eth0. https://lkml.org/lkml/2018/8/3/266 Jian-Hong Pan
