234 | * @fw_name_pre: Firmware filename prefix. The api version and extension | |
235 | * (.ucode) will be added to filename before loading from disk. The | |
236 | * filename is constructed as fw_name_pre<api>.ucode. | |
237 | * @ucode_api_max: Highest version of uCode API supported by driver. | |
238 | * @ucode_api_min: Lowest version of uCode API supported by driver. | |
239 | * @scan_antennas: available antenna for scan operation | |
240 | * @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off) | |
241 | * | |
242 | * We enable the driver to be backward compatible wrt API version. The | |
243 | * driver specifies which APIs it supports (with @ucode_api_max being the | |
244 | * highest and @ucode_api_min the lowest). Firmware will only be loaded if | |
245 | * it has a supported API version. The firmware's API version will be | |
246 | * stored in @iwl_priv, enabling the driver to make runtime changes based | |
247 | * on firmware version used. | |
248 | * | |
249 | * For example, | |
250 | * if (IWL_UCODE_API(priv->ucode_ver) >= 2) { | |
251 | * Driver interacts with Firmware API version >= 2. | |
252 | * } else { | |
253 | * Driver interacts with Firmware API version 1. | |
254 | * } | |
255 | * | |
256 | * The ideal usage of this infrastructure is to treat a new ucode API | |
257 | * release as a new hardware revision. That is, through utilizing the | |
258 | * iwl_hcmd_utils_ops etc. we accommodate different command structures | |
259 | * and flows between hardware versions as well as their API | |
260 | * versions. | |
