For a specific list of supported external 31 cards, laptops that already ship with these cards and 32 APs that come with these cards refer to ath9k wiki 33 products page: 34 35 https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/products 36 37 If you choose to build a module, it'll be called ath9k. 38 39config ATH9K_PCI 40 bool "Atheros ath9k PCI/PCIe bus support" 41 default y 42 depends on ATH9K && PCI 43 help 44 This option enables the PCI bus support in ath9k. 45 46 Say Y, if you have a compatible PCI/PCIe wireless card. 47 48config ATH9K_AHB 49 bool "Atheros ath9k AHB bus support" 50 depends on ATH9K 51 default n 52 help 53 This option enables the AHB bus support in ath9k. 54 55 Say Y, if you have a SoC with a compatible built-in 56 wireless MAC.

This should only be enabled on systems undergoing 82 certification testing and evaluation in a controlled environment. 83 Enabling this will only enable TX99 support, all other modes of 84 operation will be disabled. 85 86 TX99 support enables Specific Absorption Rate (SAR) testing. 87 SAR is the unit of measurement for the amount of radio frequency(RF) 88 absorbed by the body when using a wireless device. The RF exposure 89 limits used are expressed in the terms of SAR, which is a measure 90 of the electric and magnetic field strength and power density for 91 transmitters operating at frequencies from 300 kHz to 100 GHz. 92 Regulatory bodies around the world require that wireless device 93 be evaluated to meet the RF exposure limits set forth in the 94 governmental SAR regulations. 95 96config ATH9K_DFS_CERTIFIED 97 bool "Atheros DFS support for certified platforms" 98 depends on ATH9K && CFG80211_CERTIFICATION_ONUS 99 default n 100 help 101 This option enables DFS support for initiating radiation on 102 ath9k. There is no way to dynamically detect if a card was DFS 103 certified and as such this is left as a build time option. This 104 option should only be enabled by system integrators that can 105 guarantee that all the platforms that their kernel will run on 106 have obtained appropriate regulatory body certification for a 107 respective Atheros card by using ath9k on the target shipping 108 platforms. 109 110 This is currently only a placeholder for future DFS support, 111 as DFS support requires more components that still need to be 112 developed. At this point enabling this option won't do anything 113 except increase code size. 114 115config ATH9K_DYNACK 116 bool "Atheros ath9k ACK timeout estimation algorithm" 117 depends on ATH9K 118 default n 119 help 120 This option enables ath9k dynamic ACK timeout estimation algorithm 121 based on ACK frame RX timestamp, TX frame timestamp and frame 122 duration 123 124config ATH9K_WOW 125 bool "Wake on Wireless LAN support (EXPERIMENTAL)" 126 depends on ATH9K && PM 127 default n 128 help 129 This option enables Wake on Wireless LAN support for certain cards. 130 Currently, AR9462 is supported. 131 132config ATH9K_RFKILL 133 bool "Atheros ath9k rfkill support" if EXPERT 134 depends on ATH9K 135 depends on RFKILL=y || RFKILL=ATH9K 136 default y 137 help 138 Say Y to have ath9k poll the RF-Kill GPIO every couple of 139 seconds.
