ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devices
Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.
The wiki page for the driver is:
http://wireless.kernel.org/en/users/Drivers/ath10k
The driver has had many authors, they are listed here alphabetically:
