The following commit removed DISABLE_REGWRITE_BUFFER ops. The unnecessary
REGWRITE_BUFFER_FLUSH was not removed properly which is causing failure on
hw reset.

In the NVS/INI-parameters for the driver/firmware there is the FEM
(front end module) selection option, which may configure the hardware FEM
via autodetection or manual selection. So far, there has been support for
manual selection only.
Add support for FEM autodetection.

move paramater definitions to a device paramater structure only
leaving the device name, which antennas are used and what firmware
file to use in the iwl_cfg structure. this will not completely
remove the redundancies but greatly reduce them for devices that
only vary by name or antennas. the parameters that are more
likely to change within a given device family are left in iwl_cfg.
also separate bt param structure added to help reduce more.

This reverts commit 030725d2c7c1fafec7ede618647bf30ed79601f0.
This commit relies on commit 5ed3bc7288487bd4f891f420a07319e0b538b4fe
("mac80211: use netif_receive_skb in ieee80211_tx_status callpath")
Unfortunately not all drivers are calling ieee80211_tx_status from a
compatible context, so that commit needs to be reverted in 2.6.36.

This reverts commit 7acc7c683a747689aaaaad4fce1683fc3f85e552. It was
applied to avoid possible warning in ieee80211_restart_hw, however
reason of the warning were races in mac80211, currently hopefully fixed.
Not reseting device when performing scan is bad for two reasons.
When forcing reset from iwl_check_stuck_queue(), in case of fail,
reset will be repeated until scan finish. But since firmware is in bad
shape, scan only finish after scan_check work (about 7s). So we will
delay the reset, what is not good behaviour.
When forcing reset from iwl_recover_from_statistics(), we will not
repeat the reset, so we will not perform reset at all when needed.

The cycle counters are used by ANI to determine the amount of time that the
radio spent not receiving or transmitting. They're also used for debugging
purposes if the baseband watchdog on AR9003 detects a lockup.
In the future, we want to use these counters to determine the medium utilization
and export this information via survey. For that, we need to make sure that
the counter is only accessed from one place, which also ensures that
wraparounds won't occur at inconvenient points in time.

The calibration actual calibration flags are only used by the per chip family
source files, so it makes more sense to define them in those files instead
of globally. That way the code has to test for less flags.
Also instead of using a separate callback for testing whether a particular
calibration type is supported, simply adjust ah->supp_cals in the calibration
init which is called right after the hardware reset, before any of the
calibrations are run.

In the event of a hardware failure, reconfiguring a live connection back
with the wl1271 chip does not work as expected. The chip has management
features which require setting up the association from scratch to work
correctly. To ensure this is done every time, in managed mode, when associated,
indicate connection loss to the mac80211 before asking to reconfigure the

Due to legacy reason, dating back to when the wl1251 and wl1271 still were
a unified driver, some work-structures are initialized on hardware startup.
The hardware recovery code creates a scenario in which it is possible for a
workstruct to be re-initialized while the work-function itself is running,
which causes a kernel WARNing and a subsequent reboot.
To remedy this, move the work initialization calls to the hw allocation,
which is the logically correct place for them anyway.

Currently then dwell times for each channel in scans is set to an overly
long value, and excessive number of probe-requests are transmitted on each
channel (for active scans.)
Based on testing, comparable results can be received with smaller dwell-time,
and, with fever probe-requests - in fact, reducing the number of probe-requests
to 2 seems to increase the number of found results.
Configure more optimal values for per channel dwell times. Comparison for the
different scan configurations (in my current office environment):
dwell-time 60000 3x probe-req == ~60 results
40000 3x probe-req == ~50 results
30000 3x probe-req == ~40 results
dwell-time 60000 2x probe-req == ~70 results
40000 2x probe-req == ~60 results
30000 2x probe-req == ~58 results
The above are results for a cumulative 3 scan run. For individual scans, the
number of results drop slightly more.

Currently, the driver does not handle a failing hardware command to scan in
any way - effectively, the scan machine will jam until the driver is shut down,
and future scan requests will just return -EBUSY to user space, resulting in
a type of busy-loop. The same problem occurs if the firmware fails to deliver
the scan completion event - add timeout for this.
