mac80211: pass block ack session timeout to to driver

2017-05-20T12:27:03+00:00

commit 50ea05efaf3bed7dd34bcc2635a8b3f53bd0ccc1 upstream.

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.

mac80211: document sleep requirements for channel context ops

2015-11-03T10:15:48+00:00

Channel context driver operations can sleep, so add might_sleep()
and document this.

mac80211: call drv_stop only if driver is started

2015-11-03T09:41:12+00:00

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.
