2016-01-14mac80211: pass block ack session timeout to to driverSara Sharon1-7/+3
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 K1-0/+2
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 Peller1-0/+44
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.
