We see two options: (a) Register hwmon from the ionic driver itself, as other NIC drivers do today. (b) Have ionic create an "hwmon" auxiliary device, with a new driver in drivers/hwmon/ binding to it. The hwmon guidance in the Sashiko review prompts suggests an auxiliary driver in drivers/hwmon/ for chips whose main function isn't hardware monitoring, which would be (b). Which would you prefer? If (b), should the drivers/hwmon patch go through your tree, or would you Ack it so the whole series can go through net-next? Thanks, Nikhil
