---------------------------
What: AR9170USB
When: 2.6.40
Why: This driver is deprecated and the firmware is no longer
maintained. The replacement driver "carl9170" has been
around for a while, so the devices are still supported.

help
This driver is going to get replaced by carl9170.
This is a driver for the Atheros "otus" 802.11n USB devices.
These devices require additional firmware (2 files).
For now, these files can be downloaded from here:
http://wireless.kernel.org/en/users/Drivers/ar9170
If you choose to build a module, it'll be called ar9170usb.
