2015-05-28iwlwifi: mvm: remove code that stops multiple UMAC scans of a typeLuciano Coelho1-53/+21
We can only have one scan per type at the same time, so the code that tries to stop several scans of a type is unnecessary. Remove that to reduce code complexity.

2015-05-28iwlwifi: mvm: refactor UMAC scan UID handlingLuciano Coelho3-98/+39

2015-05-28iwlwifi: mvm: combine part of the scan stop flowsLuciano Coelho1-28/+12
For UMAC scans, we were simply jumping into another function when scan stop functions were called, while for LMAC scans, the flow continued. To make the flows cleaner and more balanced, combine the UMAC part into the main stop functions. This also makes us take one step closer into combining the state flags for both APIs. Note that some STOPPING flags will be dangling in UMAC scans, but it doesn't matter because they are not used in UMAC yet (and this will be fixed in subsequent patches).

In order to imeplement the extended VI session feature for Miracast, the FW requires to detect the VI queue. The detection of the VI queue is done when it is assigned to a STA with ADD_STA command, so by this time the FW expects the queue to be already configured (mapped to VI AC and aggregation enabled). Previously, the queue configuration was done after STA modificaton which broke the extended VI session feature and resulted in higher latencies.

However, all the products that currently require this don't have a need for the full randomisation. Therefore, advertise the feature anyway which results in host- based randomisation, done whenever the system suspends. This is sufficient for the platforms currently requiring this feature. If we ever extend this in the future to do full randomisation in the firmware, then certainly this will still be sufficient for the current requirements, so it doesn't make a lot of sense to split the feature bits.

Add support for the simplest of MediaTek Wi-Fi devices - MT7601U. It is a single stream bgn chip with no bells or whistles.

2015-05-26rtlwifi: Remove the clear interrupt routine from all driversVincent Fann5-83/+0
Several of these drivers have there TX randomly blocked for 3~5 seconds while measuring tx throughput (iperf). The root couse happens in rtl_pci_flush(). The function uses a while-loop to wait for TX queue length to decrease to 0. The TX queue length counts the number of packets that are queued in the driver. The driver relys on the TX OK interrupt to return skb and reduce TX queue length. The interrupt subroutine disables interupts, reads the interrupt registers, and then clears the registers in the beginning of _rtl_pci_interrupt(). After all interupts process are finished, the driver invokes enable_interrupt() to enable interupts. This behavior is normal for an interrupt subroutine. But enable_interrupt() invokes clear_interrupt() again. This unexpected interrupt clearing may cleari me fresh TX OK interrupts. These missing interrupts cause TX queue length to never reduce to 0i, which causes rtl_pci_flush() to be stuck in unterminated while-loop. This patch removes clear_interrupt() in enable_interrupt() to avoid this behavior.
