For a specific list of supported external 32 cards, laptops that already ship with these cards and 33 APs that come with these cards refer to ath9k wiki 34 products page: 35 36 http://wireless.kernel.org/en/users/Drivers/ath9k/products 37 38 If you choose to build a module, it'll be called ath9k. 39 40config ATH9K_PCI 41 bool "Atheros ath9k PCI/PCIe bus support" 42 default y 43 depends on ATH9K && PCI 44 ---help--- 45 This option enables the PCI bus support in ath9k. 46 47 Say Y, if you have a compatible PCI/PCIe wireless card. 48 49config ATH9K_AHB 50 bool "Atheros ath9k AHB bus support" 51 depends on ATH9K 52 default n 53 ---help--- 54 This option enables the AHB bus support in ath9k. 55 56 Say Y, if you have a SoC with a compatible built-in 57 wireless MAC.

This should only be enabled on systems undergoing 86 certification testing and evaluation in a controlled environment. 87 Enabling this will only enable TX99 support, all other modes of 88 operation will be disabled. 89 90 TX99 support enables Specific Absorption Rate (SAR) testing. 91 SAR is the unit of measurement for the amount of radio frequency(RF) 92 absorbed by the body when using a wireless device. The RF exposure 93 limits used are expressed in the terms of SAR, which is a measure 94 of the electric and magnetic field strength and power density for 95 transmitters operating at frequencies from 300 kHz to 100 GHz. 96 Regulatory bodies around the world require that wireless device 97 be evaluated to meet the RF exposure limits set forth in the 98 governmental SAR regulations. 99 100config ATH9K_DFS_CERTIFIED 101 bool "Atheros DFS support for certified platforms" 102 depends on ATH9K && CFG80211_CERTIFICATION_ONUS 103 default n 104 ---help--- 105 This option enables DFS support for initiating radiation on 106 ath9k. There is no way to dynamically detect if a card was DFS 107 certified and as such this is left as a build time option.

At this point enabling this option won't do anything 117 except increase code size. 118 119config ATH9K_DYNACK 120 bool "Atheros ath9k ACK timeout estimation algorithm (EXPERIMENTAL)" 121 depends on ATH9K 122 default n 123 ---help--- 124 This option enables ath9k dynamic ACK timeout estimation algorithm 125 based on ACK frame RX timestamp, TX frame timestamp and frame 126 duration 127 128config ATH9K_WOW 129 bool "Wake on Wireless LAN support (EXPERIMENTAL)" 130 depends on ATH9K && PM 131 default n 132 ---help--- 133 This option enables Wake on Wireless LAN support for certain cards. 134 Currently, AR9462 is supported. 135 136config ATH9K_RFKILL 137 bool "Atheros ath9k rfkill support" if EXPERT 138 depends on ATH9K 139 depends on RFKILL=y || RFKILL=ATH9K 140 default y 141 help 142 Say Y to have ath9k poll the RF-Kill GPIO every couple of 143 seconds.
