1891 * FIXME: WOW suspend mode is selected if the host sdio controller supports
1892 * both sdio irq wake up and keep power. The target pulls sdio data line to
1893 * wake up the host when WOW pattern matches. This causes sdio irq handler
1894 * is being called in the host side which internally hits ath6kl's RX path.
1895 *
1896 * Since sdio interrupt is not disabled, RX path executes even before
1897 * the host executes the actual resume operation from PM module.
1898 *
1899 * In the current scenario, WOW resume should happen before start processing
1900 * any data from the target. So It's required to perform WOW resume in RX path.
1901 * Ideally we should perform WOW resume only in the actual platform
1902 * resume path. This area needs bit rework to avoid WOW resume in RX path.
1903 *
1904 * ath6kl_check_wow_status() is called from ath6kl_rx().
