| 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 | |

| APs that come with these cards refer to ath9k wiki | |
| products page: | |
| https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/products | |

| 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. | |
