我正在尝试将ap6335的驱动加到4.2版本内核中，现在有个疑问，就是往/sys/class/rkwifi/power写１之后，用什么工具检测wifi模块是否已经通电了？
或者说，怎么判断驱动开启wifi的代码是否正确？
串口输出就这些
# echo 1 > /sys/class/rkwifi/power
[ 373.105340] wifi_power_write: poweren = 1
[ 373.109432] [WLAN_RFKILL]: rockchip_wifi_power: 1
[ 373.114429] [WLAN_RFKILL]: rockchip_wifi_ref_voltage: 1
[ 373.119723] [WLAN_RFKILL]: rockchip_wifi_ref_voltage: wifi io reference voltage control is disabled.
