Scanning currently uses the TX rate mask to restrict the rate set, which is bogus. Make it use the new set of rates from userspace. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

We were not allocating memory for the IEs passed in the scheduled_scan request and this was causing memory corruption (buffer overflow). Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
Do not send DS Channel parameter for directed probe requests in order to maximize the chance that we get a response. Some badly-behaved APs don't respond when this parameter is included.

Advertise only user-requested bitrates in a HW scan. Note that the hw_scan API doesn't currently have a way of asking for a specific probe request bitrate, so we might end up using a bitrate that we don't advertise as supported. I'll fix that later. Also add a hexdump printk to hwsim to verify this. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
When suspending, __ieee80211_suspend() calls ieee80211_scan_cancel(), which will only cancel sw scan. In order to cancel hw scan, the low-level driver has to cancel it in the suspend() callback. however, this is too late, as a new scan_work will be enqueued (while the driver is going into suspend). Add a new cancel_hw_scan() callback, asking the driver to cancel an active hw scan, and call it in ieee80211_scan_cancel().

As long as no delay is required b/w channel change, scan work is proceeding without scheduling a new work. In such case, we can not abort scan work when the card was unplugged. This patch completes the scanning immediately whenever the device goes down.

When sched_scan_stopped was called by the driver, mac80211 calls cfg80211, which in turn was calling mac80211 back with a flag "driver_initiated". This flag was used so that mac80211 would do the necessary cleanup but would not call the driver. This was enough to prevent the bounce back between the driver and mac80211, but not between mac80211 and cfg80211. To fix this, we now do the cleanup in mac80211 before calling cfg80211. To help with locking issues, the workqueue was moved from cfg80211 to mac80211.

Implement support for HW scheduled scan. The mac80211 code doesn't perform scheduled scans itself, but calls the driver to start and stop scheduled scans. This patch also creates a trace event class to be used by drv_hw_scan and the new drv_sched_scan_start and drv_sched_stop functions, in order to avoid duplicate code.
