231 * (.ucode) will be added to filename before loading from disk. The

246 * @plcp_delta_threshold: plcp error rate threshold used to trigger
247 * radio tuning when there is a high receiving plcp error rate
249 * We enable the driver to be backward compatible wrt API version. The
250 * driver specifies which APIs it supports (with @ucode_api_max being the
251 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
252 * it has a supported API version. The firmware's API version will be
253 * stored in @iwl_priv, enabling the driver to make runtime changes based
254 * on firmware version used.
257 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
258 * Driver interacts with Firmware API version >= 2.
260 * Driver interacts with Firmware API version 1.
263 * The ideal usage of this infrastructure is to treat a new ucode API
264 * release as a new hardware revision. That is, through utilizing the
265 * iwl_hcmd_utils_ops etc. we accommodate different command structures
266 * and flows between hardware versions (4965/5000) as well as their API
