pci_disable_msi() must be called if the initial request_irq() fails. Also add a warning message so it's possible to distinguish request_irq() failure and pci_enable_msi() failure. Signed-off-by: NMichal Kazior <michal.kazior@tieto.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

The private memory area in vif provided by mac80211 isn't guaranteed to be zeroed. This patch should fix issues when switching between STA and AP interface types. The tim_bitmap could become polluted by STA bssid field (since it's a union), wep_keys array could also become polluted with invalid pointers and probably much more.

Apparently the available firmware has a limit of handling 7 APs, 3 GOs or 8 STAs. This is based on empirical tests and it is still possible some combinations may crash the firmware. Signed-off-by: NMichal Kazior <michal.kazior@tieto.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

Normally user specifies broadcast ssid for scanning. If the user wants to do a passive scan it does not pass any ssids. The patch makes sure we ath10k tells firmware to not send anything at all in case it decides no ssids equals broadcast ssid.

If the device is removed and hotplug fails ioread32() will return 0xFFFFFFFF. In that case reading ringbuffer during device bringup led to out-of-bounds addressing of a ringbuffer array that in turn led to a paging failure. This could be reproduced by the following: * boot without acpi/prevent hotplug from working * insert and manually detect (pci rescan) the device * remove the device physically * load ath10k driver * kernel crashed Ringbuffer index reading is now protected by using an appropriate mask to prevent addressing an invalid array index.

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.

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.

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.

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.
