2014-07-01ath9k: Calculate sleep durationRajkumar Manoharan
Right now sleep duration is configured as beacon interval. It should be the multiple of beacon interval by listen period which helps to reduce station power consumption. Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-07-01ath9k: Increase max listen intervalRajkumar Manoharan
Earlier the listen interval is used to decide switching between operating and off-channels during bgscan and to improve throughput, the listen interval is reduced to 1. After optimiztion in scan state machine, listen period is not used for decision making and hence reverting it back to original value.

2014-07-01ath9k: Cache beacon config after associationRajkumar Manoharan
The beacon configurations are not cached properly after the station associates with AP. Not handling BEACON_INFO, is failing to update dtim period and also it is causing below warning message.

2014-06-25mac80211: support more than one band in scan requestDavid Spinadel
Some drivers (such as iwlmvm) can handle multiple bands in a single HW scan request. Add a HW flag to indicate that the driver support this. To hold the required data, create a separate structure for HW scan request that holds cfg scan request and data about different parts of the scan IEs. As this changes the mac80211 API, update all drivers using it to use the correct new function type/argument.

On some platforms, cycles_t is 64-bit, and gcc generates call to __udivdi3 for straight division of cycles_t/cycles_t.

2014-06-19wil6210: avoid dmesg pollution by Tx errorsVladimir Kondratiev
On Tx path, when vring for the destination not found, it was considered as error and message was printed unconditionally. However, this situation is normal after disconnect. If disconnect was while heavy traffic load, lots of Tx packets will be dropped and this would cause significant amount of prints in dmesg. Demote messages priority from 'error' to 'debug'.

2014-06-19wil6210: Tx performance monitoringVladimir Kondratiev
For performance monitoring, trace time intervals when Tx vring is idle/not idle. Use CPU cycle counter for this, because jiffies is too rough, and other precise time measurement methods involve overhead while get_cycles() should be fast. This used to provide some estimation for percentage when Tx vring was idle, i.e. when hardware is under-utilized. Estimation is not precise because of many reasons - CPU frequency scaling, grt_cycles() may be per core etc. But still, it is good estimation Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.
