This should only be enabled on systems undergoing 85 certification testing and evaluation in a controlled environment. 86 Enabling this will only enable TX99 support, all other modes of 87 operation will be disabled. 88 89 TX99 support enables Specific Absorption Rate (SAR) testing. 90 SAR is the unit of measurement for the amount of radio frequency(RF) 91 absorbed by the body when using a wireless device. The RF exposure 92 limits used are expressed in the terms of SAR, which is a measure 93 of the electric and magnetic field strength and power density for 94 transmitters operating at frequencies from 300 kHz to 100 GHz. 95 Regulatory bodies around the world require that wireless device 96 be evaluated to meet the RF exposure limits set forth in the 97 governmental SAR regulations. 98 99config ATH9K_DFS_CERTIFIED 100 bool "Atheros DFS support for certified platforms" 101 depends on ATH9K && CFG80211_CERTIFICATION_ONUS 102 default n 103 ---help--- 104 This option enables DFS support for initiating radiation on 105 ath9k. There is no way to dynamically detect if a card was DFS 106 certified and as such this is left as a build time option.

At this point enabling this option won't do anything 116 except increase code size. 117 118config ATH9K_DYNACK 119 bool "Atheros ath9k ACK timeout estimation algorithm (EXPERIMENTAL)" 120 depends on ATH9K 121 default n 122 ---help--- 123 This option enables ath9k dynamic ACK timeout estimation algorithm 124 based on ACK frame RX timestamp, TX frame timestamp and frame 125 duration 126 127config ATH9K_WOW 128 bool "Wake on Wireless LAN support (EXPERIMENTAL)" 129 depends on ATH9K && PM 130 default n 131 ---help--- 132 This option enables Wake on Wireless LAN support for certain cards. 133 Currently, AR9462 is supported. 134 135config ATH9K_RFKILL 136 bool "Atheros ath9k rfkill support" if EXPERT 137 depends on ATH9K 138 depends on RFKILL=y || RFKILL=ATH9K 139 default y 140 help 141 Say Y to have ath9k poll the RF-Kill GPIO every couple of 142 seconds.
