2016-09-30mac80211: add offset_tsf driver op and use it for meshPedersen, Thomas
This allows the mesh sync (and debugfs) code to make incremental TSF adjustments, avoiding any uncertainty introduced by delay in programming absolute TSF. Signed-off-by: Thomas Pedersen <twp@qca.qualcomm.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2016-09-12mac80211: refactor monitor representation in sdataAviya Erenfeld
Insert the u32 monitor flags variable in a new structure that represents a monitor interface. This will allow to add more configuration variables to that structure which will happen in an upcoming change.

2016-01-14mac80211: pass block ack session timeout to to driverSara Sharon
Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.

2015-11-03mac80211: document sleep requirements for channel context opsChaitanya T K
Channel context driver operations can sleep, so add might_sleep() and document this. Signed-off-by: Chaitanya T K <chaitanya.mgit@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-11-03mac80211: call drv_stop only if driver is startedEliad Peller
If drv_start() fails during hw_restart, all the running interfaces are being closed/stopped, which results in drv_stop() being called, although the driver was never started successfully. This might cause drivers to perform operations on uninitialized memory (as they assume it was initialized on drv_start) Consider the local->started flag, and call the driver's stop() op only if drv_start() succeeded before. Move drv_start() and drv_stop() to driver-ops.c, as they are no longer simple wrappers.
