New Revision: 244854
URL: http://svnweb.freebsd.org/changeset/base/244854
Log:
Add the initial HAL glue for the spectral analysis support.
* Finish adding the HAL capability to announce whether a NIC supports
spectral scan or not;
* Add spectral scan methods to the HAL structure;
* Add HAL_SPECTRAL_PARAM for configuration of the spectral scan logic.
The capability ID and HAL_SPECTRAL_PARAM struct are from Qualcomm
Atheros.
