---------------------------
-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.

- 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:

- If you choose to build a module, it'll be called ar9170usb.
