When issue REPLY_STATISTICS_CMD to uCode, two possible flag
can be set in the configuration flags
bit 0: Clear statistics
0: Do not clear Statistics counters
1: Clear to zero Statistics counters
Allow "clear" parameter to be set from the caller.
Add debugfs file to clear the statistics counters to help monitor and
debug the uCode behavior.

Power save request is sent from driver to uCode, but there is no
indication from uCode about the current device power save state.
Reading GP_CNTRL register bit 25:24 to show the current power save
status
00: no power save
01: MAC power down
10: PHY power down
11: Error
The uCode could switch in and out of power save mode in the order of
once per 100-300 ms in many cases. The reading here should just be used for
reference on the current uCode power save status. Do not confuse this
reading with the PowerSave set by driver and mac80211.

The iwlwifi drivers have LED blinking requirements that
mac80211 cannot fulfill due to the use of just a single
LED instead of different ones for TX, RX, radio etc.
Instead, the single LED blinks according to transfers
and is solid on the rest of the time. As such, having
LED class devices registered that mac80211 triggers are
connected to is pointless as we don't use the triggers
anyway.
Remove all the useless code and add hooks into the
driver itself. At the same time, make the LED code
abstracted so the core code that determines blink rate
etc. can be shared between 3945 and agn in iwlcore.
At the same time, the fact that we removed the use of
the mac80211 LED triggers means we can also remove the
IWLWIFI_LEDS Kconfig symbol since the LED support is
now self-contained.

Depending on required latency requested by pm_qos (via mac80211)
we can automatically adjust the sleep state. Also, mac80211 has
a user-visible dynamic sleep feature where we are supposed to
stay awake after sending/receiving frames to better receive
response frames to our packets, this can be integrated into the
sleep command.
Currently, and this patch doesn't change that yet, we default
to using sleep level 1 if PS is enabled. With a module parameter
to iwlcore, automatic adjustment to changing network latency
requirements can be enabled -- this isn't yet the default due
to requiring more testing.
The goal is to enable automatic adjustment and then go into the
deepest possible sleep state possible depending on the networking
latency requirements.
This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS
to avoid the double-timer (one in software and one in the device)
when transmitting -- the exact timeout may be ignored but that is
not of big concern.
Note also that we keep the hard-coded power indices around for
thermal throttling -- the specification of that calls for using
the specified power levels. Those can also be selected in debugfs
to allow easier testing of such parameters.

The traffic buffer will only beallocated and used if either bit 23
(IWL_DX_TX) or bit 24 (IWL_DL_RX) of "debug" is set;
example: "debug=0x800000" - log tx data traffic
"debug=0x1000000" - log rx data traffic
"debug=0x1800000" - log both tx and rx traffic
The traffic log will store the beginning portion (64 bytes) of the
latest 256 of tx and rx packets in the round-robbin buffer for
debugging,
user can examine the log through debugfs file.
How to display the current logged tx/rx traffic and txfifo and rxfifo
read/write point:
"cat traffic_log" in /sys/kernel/debug/ieee80211/phy0/iwlagn/debug
directory
By echo "0" to traffic_log file will empty the traffic log buffer and
reset both tx and rx taffic log index to 0.

Commit "iwlwifi: make debug level more user friendly" cleaned up the
debug level handling. In doing so it created a single global debug
level for all devices. Some setups do consits of more that one iwlwifi
device and in these setups there is a requirement that debug levels
should be unique per device.
We now re-introduce the per device debugging while maintaining the
cleanup effort of the previous patch.
The maintain the global debug level and now introduce a per-device debug
level that will be used if it (the per-device debug level) is set. The
per-device debug level can be controlled via the debug_level sysfs file
while the global debug level is controlled by the debug module parameter.

Add debugfs file to enable/disable HT40(40MHz) channel support.
By default, 40MHz is supported if AP can support the function.
By echo "1" to "disable_ht40" file, iwlwifi driver will disable the
40MHz support and only allow 20MHz channel.
Because the information exchange happen during association time,
so enable/disable ht40 channel only can be performed when it is not
associated with AP.

* Deprecate the "debug50" module parameter used to obtain
5000 series and up debugging. Replace it with "debug" module
parameter to match with original driver and be consistent
between them. The "debug50" module parameter can still be used,
except that the module parameter is not writable in keeping
with its previous state. We currently just mark it as "deprecated"
and do not have it in the feature-removal-schedule. Some more
cleanup of module parameters needs to be done and can then be
entered together.
* Only make "debug" module parameters visible if the driver
is compiled with CONFIG_IWLWIFI_DEBUG. This will eliminate
a lot of confusion where users think they have set debug flags
but yet cannot see any debug output.
* Make module parameters writable. This eliminates the need for the
"debug_level" sysfs file, which can now also be deprecated and
added to feature-removal-schedule. This file is in significant
use though with many iwlwifi documents and text referring users
to it. We can thus not take its removal lightly and keep it around.
With iwlcore shared between iwlagn and iwl3945 we really do not need
debug module parameters for each but can instead have one debug
module parameter for the iwlcore module. The same issue is here as
with the sysfs file - a lot of iwlwifi documentation and text (like
bug reports) rely on iwlagn and iwl3945 having this module parameter,
so changing this to a module parameter of iwlcore will have significant
impact and we do not do this for that reason.
One consequence of this patch is that if a user is running a system
with both 3945 and later hardware then the setting of the one module
parameter will affect the value of the other. The likelihood of this
seems low - and even if this setup is present it does not seem like an
issue for both modules to run with the same debug level.
