Re: [RFC] Appropriate subsystem/UAPI for Semtech SX126x packet radio support

Is stacking protocols on top of the MAC that different to IEEE

802.15.4?

Had a look through `mac802154` and `ieee802154_ops`, the hardware boundary does look quite similar, particularly packet TX/RX, start/stop, TX power and energy detection.

The main differences seem to be the 802.15.4-specific parts such as channel/page addressing, CSMA parameters and address filtering, versus PHY-specific configuration for LoRa/GFSK.

Would it make sense to investigate factoring out a small generic packet-radio layer beneath the MAC-specific interfaces?

Thanks,
