All AR9170 hardware have a 16-Bit random number generator. The documentation claims the values are suitable for "security keys". The "throughput" is around 320Kibit/s. It's slow, but it does work without introducing any special offload firmware commands. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.

This is another driver for the Atheros "otus" 802.11n USB devices.
|
|
|
|
This driver provides more features than the original,
|
|
but it needs a special firmware (carl9170-1.fw) to do that.
|
|
|
|
The firmware can be downloaded from our wiki here:

If you choose to build a module, it'll be called carl9170.

Say Y, unless you need the LEDs for firmware debugging.
