| 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 |

| help |
| 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 |
| bool "Atheros DFS support for certified platforms" |
| 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. |

| Say Y to have ath9k poll the RF-Kill GPIO every couple of |
| seconds. Turn off to save power, but enable it if you have |
| a platform that can toggle the RF-Kill GPIO. |
| |
| config ATH9K_CHANNEL_CONTEXT |

| help |
| This separate driver provides a loader in order to support the |
| AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have |
| their initialization data (which contains the real PCI Device ID |
| that ath9k will need) stored together with the calibration data out |
| of reach for the ath9k chip. |
| |
| These devices are usually various network appliances, routers or |
| access Points and such. |
