  183. * struct iwl_cfg
  184. * @fw_name_pre: Firmware filename prefix. The api version and extension
  185. * (.ucode) will be added to filename before loading from disk. The
  186. * filename is constructed as fw_name_pre<api>.ucode.
  187. * @ucode_api_max: Highest version of uCode API supported by driver.
  188. * @ucode_api_min: Lowest version of uCode API supported by driver.
  189. *
  190. * We enable the driver to be backward compatible wrt API version. The
  191. * driver specifies which APIs it supports (with @ucode_api_max being the
  192. * highest and @ucode_api_min the lowest). Firmware will only be loaded if
  193. * it has a supported API version. The firmware's API version will be
  194. * stored in @iwl_priv, enabling the driver to make runtime changes based
  195. * on firmware version used.
  196. *
  197. * For example,
  198. * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
  199. * Driver interacts with Firmware API version >= 2.
  200. * } else {
  201. * Driver interacts with Firmware API version 1.
  202. * }
  203. *
  204. * The ideal usage of this infrastructure is to treat a new ucode API
  205. * release as a new hardware revision. That is, through utilizing the
  206. * iwl_hcmd_utils_ops etc. we accommodate different command structures
  207. * and flows between hardware versions (4965/5000) as well as their API
  208. * versions.
