2017-01-10staging: wilc1000: Connect to highest RSSI value for required SSIDAditya Shankar
Connect to the highest rssi with the required SSID in the shadow table if the connection criteria is based only on the SSID. For the first matching SSID, an index to the table is saved. Later the index is updated if matching SSID has a higher RSSI value than the last saved index. However if decision is made based on BSSID, there is only one match in the table and corresponding index is used. changes in v2: initialize sel_bssi_idx to UINT_MAX. Combine two checks for identifying sel_bssi_idx value for a SSID. Signed-off-by: Aditya Shankar <aditya.shankar@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Not as big as 4.9 was, but still just over a thousand changes. We almost broke even of lines added vs. removed, as the slicoss driver was removed (got a "clean" driver for the same hardware through the netdev tree), and some iio drivers were also dropped, but I think we ended up adding a few thousand lines to the source tree in the end. Other than that it's a lot of minor fixes all over the place, nothing major stands out at all. All of these have been in linux-next for a while.

2016-07-06nl80211: support beacon report scanningAvraham Stern
Beacon report radio measurement requires reporting observed BSSs on the channels specified in the beacon request. If the measurement mode is set to passive or active, it requires actually performing a scan (passive or active, accordingly), and reporting the time that the scan was started and the time each beacon/probe was received (both in terms of TSF of the BSS of the requesting AP). If the request mode is table, this information is optional. In addition, the radio measurement request specifies the channel dwell time for the measurement. In order to use scan for beacon report when the mode is active or passive, add a parameter to scan request that specifies the channel dwell time, and add scan start time and beacon received time to scan results information. Supporting beacon report is required for Multi Band Operation (MBO).

2016-06-25staging: wilc1000: Change interface wilc_mq_send to wilc_enqueue_cmdBinoy Jayan
Replace the interface 'wilc_mq_send' with 'wilc_enqueue_cmd' and remove the now unused structures 'message' and 'message_queue'. Restructure switch statement in the work queue helper function host_if_work and remove unwanted indentation.

2016-06-25staging: wilc1000: Replace kthread with workqueue for host interfaceBinoy Jayan
Deconstruct the kthread / message_queue logic, replacing it with create_singlethread_workqueue() / queue_work() setup, by adding a 'struct work_struct' to 'struct host_if_msg'. The current kthread hostIFthread() is converted to a work queue helper with the name 'host_if_work'.

2016-06-25staging: wilc1000: message_queue: Move code to host interfaceBinoy Jayan
Move the contents of wilc_msgqueue.c and wilc_msgqueue.h into host_interface.c, remove 'wilc_msgqueue.c' and 'wilc_msgqueue.h'. This is done so as to restructure the implementation of the kthread 'hostIFthread' using a work queue.

2016-06-25staging: wilc1000: Remove semaphore close_exit_syncBinoy Jayan
The semaphore 'close_exit_sync' does not serve any purpose other than delaying the deregistration of the device which it is trying to protect from shared access. 'up' is called only when a subdevice is closed and not when it is opened. So, the semaphore count only goes up when the device is used.

The semaphore 'sync_event' is used as completion, so convert it to a struct completion type. Also, return -ETIME if the return value of wait_for_completion_timeout is 0.

2016-06-25staging: wilc1000: Replace semaphore txq_add_to_head_cs with mutexBinoy Jayan
The semaphore 'txq_add_to_head_cs' is a simple mutex, so it should be written as one. Semaphores are going away in the future. Also, removing the timeout scenario as the error handling code does not propagate the timeout properly.
