  190. * (.ucode) will be added to filename before loading from disk. The
  191. * filename is constructed as fw_name_pre<api>.ucode.
  192. * @ucode_api_max: Highest version of uCode API supported by driver.
  193. * @ucode_api_min: Lowest version of uCode API supported by driver.
  194. * @pa_type: used by 6000 series only to identify the type of Power Amplifier
  195. * @max_ll_items: max number of OTP blocks
  196. * @shadow_ram_support: shadow support for OTP memory
  197. * @use_rts_for_ht: use rts/cts protection for HT traffic
  198. *
  199. * We enable the driver to be backward compatible wrt API version. The
  200. * driver specifies which APIs it supports (with @ucode_api_max being the
  201. * highest and @ucode_api_min the lowest). Firmware will only be loaded if
  202. * it has a supported API version. The firmware's API version will be
  203. * stored in @iwl_priv, enabling the driver to make runtime changes based
  204. * on firmware version used.
  205. *
  206. * For example,
  207. * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
  208. * Driver interacts with Firmware API version >= 2.
  209. * } else {
  210. * Driver interacts with Firmware API version 1.
  211. * }
  212. *
  213. * The ideal usage of this infrastructure is to treat a new ucode API
  214. * release as a new hardware revision. That is, through utilizing the
  215. * iwl_hcmd_utils_ops etc. we accommodate different command structures
  216. * and flows between hardware versions (4965/5000) as well as their API
  217. * versions.
