Wey-Yi Guy fa8f130c50 iwlwifi: code cleanup for connectivity recovery
Split the connectivity check and recovery routine into separated
functions based on the types
   1. iwl_good_ack_health() - check for ack count
   2. iwl_good_plcp_health() - check for plcp error

Based on the type of errors being detected, different recovery methods
will be used to bring the system back to normal operational state.

Because different NIC has different HW and uCode, the behavior is also
different; these functions thus now form part of the ops infrastructure,
so we can have more control on how to monitor and recover from error condition
case per device.

Wey-Yi Guy b74e31a9bc iwlwifi: Recover TX flow stall due to stuck queue
Monitors the internal TX queues periodically.  When a queue is stuck
for some unknown conditions causing the throughput to drop and the
transfer is stop, the driver will force firmware reload and bring the
system back to normal operational state.

The iwlwifi devices behave differently in this regard so this feature is

Ben Cahill ed56a3f15a iwlwifi: Add chain_noise support for 6050
Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset).  As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate
chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and
remove those for 6050.

Reinette Chatre 3459ab5a1c iwlwifi: make broadcast station addition generic
Add function pointer for broadcast station addition so that we can call it
in from iwlcore at a later time. We only distinguish between iwlagn and
iwl3945 broadcast station addition. For the iwl3945 station addition we add
that function to iwlcore since that is where most station functionality
resides, making it part of iwl3945 will require significant code
reorganization that will dilute station management functionality. This
seems to be an efficient solution.

It may seem as though we are removing error checking when adding the 3945
broadcast station but this error checking was never really necessary since
the function returns the station id and the broadcast station id is always
set.

Trieu 'Andrew' Nguyen 3e4fb5faef iwlwifi: Tune radio to prevent unexpected behavior
We have seen the throughput dropped due to external noisy environment
and the radio is out of tune.  There are lot of plcp errors indicating
this condition. Eventually the station can get de-authenticated by the
Access Point.  By resetting and tuning the radio, the plcp errors are
reduced or eliminated and the throughput starts to rise.

To prevent unexpected behavior such as drop in throughput or deauthentication,
- The change provides the driver feature to monitor and tune the radio base on
the statistics notification from the uCode.
- It also allows the setting of the plcp error rate threshold via
the plcp_delta under debugfs interface.

Johannes Berg e932a609e9 iwlwifi: LED cleanup
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.

Johannes Berg 78f5fb7fc6 iwlwifi: support idle for 6000 series hw
Using powersave while idle saves a lot of power, but
we've had problems with this on some cards (5150 has
been reported to be problematic). However, on the new
6000 series we're seeing no problems, so for now let
that hardware benefit from idle mode, we can look at
the problems with other hardware one by one and then
enable those once we figure out the problems.
