213 * We enable the driver to be backward compatible wrt API version. The
214 * driver specifies which APIs it supports (with @ucode_api_max being the
215 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
216 * it has a supported API version. The firmware's API version will be
217 * stored in @iwl_priv, enabling the driver to make runtime changes based
218 * on firmware version used.
220 * For example,
221 * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
222 * Driver interacts with Firmware API version >= 2.
223 * } else {
224 * Driver interacts with Firmware API version 1.
227 * The ideal usage of this infrastructure is to treat a new ucode API
228 * release as a new hardware revision. That is, through utilizing the
229 * iwl_hcmd_utils_ops etc. we accommodate different command structures
230 * and flows between hardware versions (4965/5000) as well as their API
231 * versions.
