3 tristate "Linux Community AR9170 802.11n USB support"
4 depends on USB && MAC80211
9 This is the mainline driver for the Atheros "otus" 802.11n USB devices.
11 It needs a special firmware (carl9170-1.fw), which can be downloaded
13 <https://wireless.wiki.kernel.org/en/users/Drivers/carl9170>
15 If you choose to build a module, it'll be called carl9170.
18 bool "SoftLED Support"
21 depends on MAC80211_LEDS
23 This option is necessary, if you want your device's LEDs to blink.
25 Say Y, unless you need the LEDs for firmware debugging.
27 config CARL9170_DEBUGFS
28 bool "DebugFS Support"
29 depends on CARL9170 && DEBUG_FS && MAC80211_DEBUGFS
32 Export several driver and device internals to user space.
38 depends on CARL9170 && (INPUT = y || INPUT = CARL9170)
42 bool "Random number generator"
43 depends on CARL9170 && (HW_RANDOM = y || HW_RANDOM = CARL9170)
46 Provides a hardware random number generator to the kernel.
48 SECURITY WARNING: It's relatively easy to eavesdrop all
49 generated random numbers from the transport stream with
50 usbmon [software] or special usb sniffer hardware.
52 Say N, unless your setup[i.e.: embedded system] has no
53 other rng source and you can afford to take the risk.
