Is the rfkill input active high or low? (wdr3600)


According to /sys/kernel/debug/gpio, gpio-17 is the rfkill switch on the WDR3600.
I wondered if wireless will be disabled when that input reads "hi" or "lo"?

cat /sys/kernel/debug/gpio
gpiochip0: GPIOs 0-31, parent: platform/ath79-gpio, ath79-gpio:
 gpio-11  (                    |tp-link:green:usb1  ) out hi
 gpio-12  (                    |tp-link:green:usb2  ) out hi
 gpio-13  (                    |tp-link:blue:wlan2g ) out lo
 gpio-14  (                    |tp-link:blue:system ) out lo
 gpio-15  (                    |tp-link:blue:qss    ) out hi
 gpio-16  (                    |QSS button          ) in  hi
 gpio-17  (                    |RFKILL switch       ) in  lo
 gpio-18  (                    |external LNA0       ) out hi
 gpio-19  (                    |external LNA1       ) out hi
 gpio-21  (                    |USB2 power          ) out hi
 gpio-22  (                    |USB1 power          ) out hi

gpiochip2: GPIOs 473-488, ath9k-phy1:
 gpio-473 (                    |ath9k-phy1          ) out hi

gpiochip1: GPIOs 489-511, ath9k-phy0:
 gpio-490 (                    |ath9k-phy0          ) in  lo

any quick and easy way to simply disable that switch so that wifi always remains enabled?

From memory if you just remove the simlink /etc/rc.buttons/rfkill then the button handler won't trigger for that specific button anymore.
