 220  * struct iwl_cfg
 221  * @fw_name_pre: Firmware filename prefix. The api version and extension
 222  *      (.ucode) will be added to filename before loading from disk. The
 223  *      filename is constructed as fw_name_pre<api>.ucode.
 224  * @ucode_api_max: Highest version of uCode API supported by driver.
 225  * @ucode_api_min: Lowest version of uCode API supported by driver.
 226  * @pa_type: used by 6000 series only to identify the type of Power Amplifier
 227  * @max_ll_items: max number of OTP blocks
 228  * @shadow_ram_support: shadow support for OTP memory
 229  * @led_compensation: compensate on the led on/off time per HW according
 230  *      to the deviation to achieve the desired led frequency.
 231  *      The detail algorithm is described in iwl-led.c
 232  * @use_rts_for_ht: use rts/cts protection for HT traffic
 233  * @chain_noise_num_beacons: number of beacons used to compute chain noise
 234  * @adv_thermal_throttle: support advance thermal throttle
 235  * @support_ct_kill_exit: support ct kill exit condition
 236  * @support_wimax_coexist: support wimax/wifi co-exist
 237  * @plcp_delta_threshold: plcp error rate threshold used to trigger
 238  *      radio tuning when there is a high receiving plcp error rate
 239  *
 240  * We enable the driver to be backward compatible wrt API version. The
 241  * driver specifies which APIs it supports (with @ucode_api_max being the
 242  * highest and @ucode_api_min the lowest). Firmware will only be loaded if
 243  * it has a supported API version. The firmware's API version will be
 244  * stored in @iwl_priv, enabling the driver to make runtime changes based
 245  * on firmware version used.
 246  *
 247  * For example,
 248  * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
 249  *      Driver interacts with Firmware API version >= 2.
 250  * } else {
 251  *      Driver interacts with Firmware API version 1.
 252  * }
 253  *
 254  * The ideal usage of this infrastructure is to treat a new ucode API
 255  * release as a new hardware revision. That is, through utilizing the
 256  * iwl_hcmd_utils_ops etc. we accommodate different command structures
 257  * and flows between hardware versions (4965/5000) as well as their API
 258  * versions.
