That driver contains a binary-only part.
<quote> 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
http://ftp.fcc.gov/Bureaus/Engineering_Technology/Orders/2001/fcc01264.pdf
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". </quote>
