I see two options for that:

- Add
	select HWMON
  to the NET_DSA Kconfig entry.
  Example is Broadcom TIGON3 driver.

- Add a DSA_HWMON Kconfig entry to define the dependencies and
  to let the user select if the functionality should be enabled.
  Example is Intel IGB driver.

Any preference from your side ? If no, I'll go with the latter.

Probably the latter is better, select can get you into trouble.
