2014-09-23ath10k: unify wmi event function namesMichal Kazior

2014-09-23ath10k: deduplicate wmi service ready logicMichal Kazior
The logic responsible for processing the event is no different across different firmware binaries. The difference that needs to be dealt with is the ABI of data structures. The intermediate structure uses __le32 to avoid extra memory allocations to byteswap variable-length substructures (i.e. host mem chunks).

2014-09-23ath10k: fix tx/rx chainmask initMichal Kazior
Firmware reports the number of RF chains so use that for initialization of supp_{tx,rx}_chainmask instead of using a macro for 3x3 chips.

2014-09-23ath10k: workaround fw beaconing bugMichal Kazior
Some firmware revisions don't wait for beacon tx completion before sending another SWBA event. This could lead to hardware using old (freed) beacon data in some cases, e.g. tx credit starvation combined with missed TBTT. This is very very rare. On non-IOMMU-enabled hosts this could be a possible security issue because hw could beacon some random data on the air. On IOMMU-enabled hosts DMAR faults would occur in most cases and target device would crash. Since there are no beacon tx completions (implicit nor explicit) propagated to host the only workaround for this is to allocate a DMA-coherent buffer for a lifetime of a vif and use it for all beacon tx commands. Worst case for this approach is some beacons may become corrupted, e.g. garbled IEs or out-of-date TIM bitmap. Keep the original beacon-related code as-is in case future firmware revisions solve this problem so that the old path can be easily re-enabled with a fw_feature flag.

2014-09-02ath10k: re-enable interrupts properly in hw recoveryMichal Kazior
Recent changes done to start/restart sequences broke hw recovery in some hw configurations. The pci transport was stopped twice however due to a workaround in the pci disabling code the disable/enable for first msi interrupt was not balanced. This ended up with irqs not being properly re-enabled and the following print out during recovery: ath10k: failed to receive control response completion, polling.. ath10k: Service connect timeout: -110 ath10k: Could not init core: -110 Legacy interrupt mode was unaffected while msi ranged mode would be partially crippled (it would miss fw indication interrupts but otherwise it worked fine). This fixes completely broken fw recovery for a single msi interrupt mode and fixes subsequent fw crash reports for msi range interrupt mode.

This fixes two corner cases. One is a race between disabling copy engine interrupts and unhandled pending interrupts on the host.
