1617 * @ucode_api_max: Highest version of uCode API supported by driver.
1618 * @ucode_api_min: Lowest version of uCode API supported by driver.

1620 * @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
1621 *
1622 * We enable the driver to be backward compatible wrt API version. The
1623 * driver specifies which APIs it supports (with @ucode_api_max being the
1624 * highest and @ucode_api_min the lowest). Firmware will only be loaded if
1625 * it has a supported API version. The firmware's API version will be
1626 * stored in @il_priv, enabling the driver to make runtime changes based
1627 * on firmware version used.
1628 *
1629 * For example,
1630 * if (IL_UCODE_API(il->ucode_ver) >= 2) {
1631 *	Driver interacts with Firmware API version >= 2.

1633 *	Driver interacts with Firmware API version 1.
1634 * }
1635 *
1636 * The ideal usage of this infrastructure is to treat a new ucode API
1637 * release as a new hardware revision. That is, through utilizing the
1638 * il_hcmd_utils_ops etc. we accommodate different command structures
1639 * and flows between hardware versions as well as their API
1640 * versions.
