299 * it has a supported API version. The firmware's API version will be
300 * stored in @iwl_priv, enabling the driver to make runtime changes based
301 * on firmware version used.

310 * The ideal usage of this infrastructure is to treat a new ucode API

313 * and flows between hardware versions (4965/5000) as well as their API
314 * versions.
