219 | * We enable the driver to be backward compatible wrt API version. The | |
220 | * driver specifies which APIs it supports (with @ucode_api_max being the | |
221 | * highest and @ucode_api_min the lowest). Firmware will only be loaded if | |
222 | * it has a supported API version. The firmware's API version will be | |
223 | * stored in @iwl_priv, enabling the driver to make runtime changes based | |
224 | * on firmware version used. | |
225 | * | |
226 | * For example, | |
