This module adds support for wireless adapters based on

Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family

of chipsets. For a specific list of supported external

cards, laptops that already ship with these cards and

If you choose to build a module, it'll be called ath9k.

Say N. This should only be enabled on systems undergoing
|
certification testing and evaluation in a controlled environment.
|
Enabling this will only enable TX99 support, all other modes of
|
operation will be disabled.
|
|
TX99 support enables Specific Absorption Rate (SAR) testing.
|
SAR is the unit of measurement for the amount of radio frequency(RF)
|
absorbed by the body when using a wireless device. The RF exposure
|
limits used are expressed in the terms of SAR, which is a measure
|
of the electric and magnetic field strength and power density for
|
transmitters operating at frequencies from 300 kHz to 100 GHz.
|
Regulatory bodies around the world require that wireless device
|
be evaluated to meet the RF exposure limits set forth in the
|
governmental SAR regulations.

config ATH9K_DFS_CERTIFIED

depends on ATH9K && CFG80211_CERTIFICATION_ONUS
|
default n
|
help
|
This option enables DFS support for initiating radiation on
|
ath9k. There is no way to dynamically detect if a card was DFS
|
certified and as such this is left as a build time option. This
|
option should only be enabled by system integrators that can
|
guarantee that all the platforms that their kernel will run on
|
have obtained appropriate regulatory body certification for a
|
respective Atheros card by using ath9k on the target shipping
|
platforms.
|
|
This is currently only a placeholder for future DFS support,
|
as DFS support requires more components that still need to be
|
developed. At this point enabling this option won't do anything
|
except increase code size.
