That driver contains a binary-only part.

The ath_hal module contains the Atheros Hardware Access Layer (HAL).
This code manages much of the chip-specific operation of the driver.
The HAL is provided in a binary-only form in order to comply with FCC
regulations. In particular, a radio transmitter can only be operated at
power levels and on frequency channels for which it is approved. The FCC
requires that a software-defined radio cannot be configured by a user
to operate outside the approved power levels and frequency channels.
This makes it difficult to open-source code that enforces limits on
the power levels, frequency channels and other parameters of the radio
transmitter. See

for the specific FCC regulation. Because the module is provided in a
binary-only form it is marked "Proprietary"; this means when you load
it you will see messages that your system is now "tainted".

US was a free country. It gets worse by the day.
