ath10k: refactor radar detection code If 20MHz CAC completed successfully then subsequent CAC with wider bandwidth (40Mhz, 80Mhz) with identical control frequency did not start monitor vdev making it impossible to detect any radar pulses during intended CAC. It also was incorrect to assume ath10k_config() will be called after CAC is finished. Theoretically for non-HT channels nothing changes between CAC and start_ap() (albeit in practice this can be different). The incorrect assumption led to CAC not being stopped on non-HT chandefs leading to all Rx being drooped making it impossible for clients to associate.

ath10k: refactor monitor code It was possible to create/delete/start/stop monitor vdev from a few places that were not exclusively protected against each other. This resulted in monitor vdev being stopped/removed by one call origin while another one was expecting it to continue running. For example if CAC was started and interface's promiscuous mode was toggled monitor vdev was removed from the driver meaning no radar would be detected. In additional a warning would be printed upon CAC completion complaining it tried to stop non-running monitor vdev. The patch simplifies monitor code by removing IEEE80211_HW_WANT_MONITOR_VIF (which wasn't really ever needed) and improves state tracking. It also unifies prints.

The in-driver calculation was introduced prior (commit ddcc347b70 mac80211: fix rx_nss calculation for drivers with hw rc). Since it's fixed, use mac80211 provided value from now.

ath10k: detect the number of spatial streams supported by hw Until now ath10k assumed 3 spatial streams. However some devices support only 2 spatial streams. This patch improves performance on devices that don't support 3 spatial streams. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

ath10k: improve tx throughput on slow machines It is more efficient to move just the 802.11 header instead of the whole payload in most cases. This has no measurable effect on modern hardware. It should improve performance by a few percent on hardware such as an Access Point that have a slow CPU compared to a typical desktop CPU.

ath10k: implement device recovery Restart the hardware if FW crashes. If FW crashes during recovery we leave the hardware in a "wedged" state to avoid recursive recoveries. When in "wedged" state userspace may bring interfaces down (to issue stop()) and then bring one interface (to issue start()) to reload hardware manually.

ath10k: defer hw setup to start/stop mac80211 hooks This fixes suspend-to-disk. The hardware is now re-initialized upon freeze/thaw properly. This also makes suspend/resume re-initialize the hardware as WoWLAN support is not done yet. With some little work it should be possible to support hw reconfiguration for hw/fw recovery. HW must be initialized once before registering to mac80211 because FW determinates what hw capabilities can be advertised.

ath10k: decouple suspend code Split up fw-related and hw-related suspension code. Although we don't advertise WoW support to mac80211 yet it's useful to keep the code in suspend/resume hooks. At this point there's no need to keep pci pm ops. In case of WoW mac80211 calls ath10k_suspend() which should take care of entering low-power mode. In case WoW is not available mac80211 will go through regular interface teradown and use start/stop.

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>
