2014-02-13ath10k: AP: handle HT station which does not have HT RX MCSBartosz Markowski
This is a workaround for HT-enabled STAs which break the spec and have no HT capabilities RX mask (no HT RX MCS map). As per spec, in section 20.3.5 Modulation and coding scheme (MCS), MCS 0 through 7 are mandatory in 20MHz with 800 ns GI at all STAs. Firmware asserts if such situation occurs.

2014-02-13ath10k: suspend hardware before resetMarek Puzyniak

2014-02-13ath10k: fix device initialization routineMichal Kazior
Hardware CUS232 version 2 has some issues with cold reset that lead to Data Bus Errors or system hangs in some cases. It's safer to use warm reset when possible as it shouldn't trigger the aforementioned issues. Prefer warm reset over cold reset. However since warm reset doesn't work after FW crash make sure to fallback to cold reset when booting up the HW.

2014-02-13ath10k: Set proper nss value for the peerMarek Kwaczynski
It was found during testing the nss calculation does not cover all corner cases. Station could request eq. only MCS8 and MCS9 (nss=2 specific). Next num_rates=2 so the driver sets nss=(max((2+7)/8, 1))=1. Which is wrong. 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. End user will experience lower throuhputs than expected if the nss is wrongly calculated.

2014-01-30ath10k: configure access category for arpMarek Puzyniak
ARP frames exchange does not work properly for UAPSD enabled AP. ARP requests which arrives with access category 0 are processed by network stack and send back with access category 0. FW changes access category to 6. This is causing problems when UAPSD associated STA is sleeping after has sent ARP request. Configure ARP access category in FW to best effort (0) solves this problem. ARP frames will be send with access category 0. Simplify arp ac override functionality by removing redundant entry in pdev param maping table.

2013-11-27ath10k: defer irq registration until hif start()Michal Kazior
It's impossible to rely on disable_irq() and/or CE interrupt masking with legacy shared interrupts. Other devices sharing the same irq line may assert it while ath10k is doing something that requires no interrupts. Irq handlers are now registered after all preparations are complete so spurious/foreign interrupts won't do any harm. The handlers are unregistered when no interrupts are required (i.e. during driver teardown). This also removes the ability to receive FW early indication (since interrupts are not registered until early boot is complete). This is not mission critical (it's more of a hint that early boot failed due to unexpected FW crash) and will be re-added in a follow up patch.

2013-11-27ath10k: don't use interrupts for BMIMichal Kazior
It's not really necessary for interrupts to be used for BMI. BMI already assumes there's only one caller at a time and it works directly with CE. Make BMI poll for CE completions instead of waiting for interrupts. This makes disabling interrupts during early boot possible.

2013-11-27ath10k: split up pci irq codeMichal Kazior
Hardware waits until host signals whether it has chosen MSI(-X) or shared legacy interrupts. It is not required for the driver to register interrupt handlers immediately. This patch prepares the pci irq code for more changes. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
