| * struct iwl_cfg |
| * @fw_name_pre: Firmware filename prefix. The api version and extension |
| * (.ucode) will be added to filename before loading from disk. The |
| * filename is constructed as fw_name_pre<api>.ucode. |
| * @ucode_api_max: Highest version of uCode API supported by driver. |
| * @ucode_api_min: Lowest version of uCode API supported by driver. |
| * @pa_type: used by 6000 series only to identify the type of Power Amplifier |
| * @max_ll_items: max number of OTP blocks |
| * @shadow_ram_support: shadow support for OTP memory |
| * @led_compensation: compensate on the led on/off time per HW according |
| * to the deviation to achieve the desired led frequency. |
| * The detail algorithm is described in iwl-led.c |
| * @use_rts_for_ht: use rts/cts protection for HT traffic |
| * @chain_noise_num_beacons: number of beacons used to compute chain noise |
| * |
| * We enable the driver to be backward compatible wrt API version. The |
| * driver specifies which APIs it supports (with @ucode_api_max being the |
| * highest and @ucode_api_min the lowest). Firmware will only be loaded if |
| * it has a supported API version. The firmware's API version will be |
| * stored in @iwl_priv, enabling the driver to make runtime changes based |
| * on firmware version used. |
| * |
| * For example, |
| * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { |
| * Driver interacts with Firmware API version >= 2. |
| * } else { |
| * Driver interacts with Firmware API version 1. |
| * } |
| * |
| * The ideal usage of this infrastructure is to treat a new ucode API |
| * release as a new hardware revision. That is, through utilizing the |
| * iwl_hcmd_utils_ops etc. we accommodate different command structures |
| * and flows between hardware versions (4965/5000) as well as their API |
| * versions. |
