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).

lbs_mac_event_disconnected may free priv->currenttxskb
while lbs_hard_start_xmit accesses to it.
The patch adds a spinlock for mutual exclusion.
Tested on OLPC XO-1 (usb8388) and XO-1.5 (sd8686) with v4.7-rc3.
Confirmed that lbs_mac_event_disconnected is being called on the
station when hostapd on access point is given SIGHUP.

alloc_workqueue replaces deprecated create_workqueue().
In if_sdio.c, the workqueue card->workqueue has workitem
&card->packet_worker, which is mapped to if_sdio_host_to_card_worker.
The workitem is involved in sending packets to firmware.
Forward progress under memory pressure is a requirement here.
In if_spi.c, the workqueue card->workqueue has workitem
&card->packet_worker, which is mapped to if_spi_host_to_card_worker.
The workitem is involved in sending command packets from the host.
Forward progress under memory pressure is a requirement here.
Dedicated workqueues have been used in both cases since the workitems
on the workqueues are involved in normal device operation with
WQ_MEM_RECLAIM set to gurantee forward progress under memory pressure.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary.
flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty. Hence the calls to flush_workqueue() before
destroy_workqueue() have been dropped.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

This patch adds an interface for handling commands like
iwconfig wlanX power on/off. Such an interface formerly existed
when the driver used wext.
While performance with sdio in polling mode without using
powersave mode is quite bad, powersaving mode is unusable,
so do not enable it under such conditions.

When the device is remove e.g. because of going to suspend
mode with powersaving enabled, lbs_remove_card tries to exit
powersaving state even when already woken up. That command is
not processed properly in that situation, since the command
processing queue is already stopped, so it waits forever
for the command being processed, so disable it.

Removes the old todo block and checks only whether ieee powersave
mode is requested. We still have to check for being connected as
this powersave mode includes logic for regularly waking up and
checking for packets which only makes sense when connected.
For not being connected, another mode is needed.

If the main thread gets one PS AWAKE event and one PS SLEEP event
in one iteration over event_fifo there will never be checks for

If a sdio host does not support sdio irqs, polling is used
instead. That has an impact on performance. Some functionality
should not be enabled then. This add a variable in
libertas_priv to indicate that.

struct cmd_ds_802_11_ps_mode
contains the command header and a pointer to it was
initialized with data points to the body which leads to
mis-interpretation of the cmd_ds_802_11_ps_mode.action member.
cmd[0] contains the header, &cmd[1] points beyond that.
cmdnode->cmdbuf is a pointer to the command buffer
This piece of code was unused since power saving was
