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: Bartosz Markowski <bartosz.markowski@tieto.com> Janusz Dziedzic <janusz.dziedzic@tieto.com> Kalle Valo <kvalo@qca.qualcomm.com> Marek Kwaczynski <marek.kwaczynski@tieto.com> Marek Puzyniak <marek.puzyniak@tieto.com> Michal Kazior <michal.kazior@tieto.com> Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
