>From your email I gather I have a RFKILL switch but it needs to be
"enabled" in the device driver. I will scour the ath9k source code for
this config.
Thank you for your input.

Hi,
So the 30 second version of rfkill is this:
* it can be software driven (ie, the driver implements rfkill by
stopping TX/RX and baseband activity, possibly shutting down the NIC)
* it can be hardware driven (ie, there's an RFKill line to the NIC via a
GPIO pin)
The pin itself can be controlled by:
* hardware - ie, a physical switch to the rfkill pin;
* software - ie, some ACPI controlled function maps to the rfkill pin.
What you have above seems to be (2) and (1) respectively - ie, that pin
is mapped to GPIO7 on the NIC, and now you need to program GPIO7 to be
an RFkill pin. There's code in ath9k somewhere to configure the GPIO pin
correctly to implement hardware rfkill.
Good luck!
Adrian
