2c810ccdba iwlwifi: rework broadcast station management
Currently, the broadcast station is managed along
with the interface type, rather than always being
present. That leads to a bug with injection -- it
is currently not possible to inject frames when
the only virtual interface is a monitor, because
in that the required broadcast station is missing.

Additionally, allocating and deallocating the
broadcast station's LQ all the time is wasteful,
and the code to support this is fairly complex.

So this changes completely the way we manage the
broadcast station. Rather than manage it along
with any interface, we now allocate it when we
bring the device up, and remove it again when we
bring the device down. When we bring the device
up, we don't immediately program the broadcast
station into it, instead we just mark it active
and rely on the next restore cycle to upload it
to the device. This works because an unassociated
RXON is always required at least once to set up
device parameters, which implies a reprogramming
of stations into the device.

As we now manage all stations properly, there no
longer is a need for forcing a clearing of them
via iwl_clear_ucode_stations(), which can become
a lot simpler.

22adba2a69 iwlwifi: remove ucode virtual functions
AGN devices all use the same ucode operations,
except for 4965, because 4965 uses only v1 file
headers.

Therefore, we can remove all the indirection
we have here and just code the API distinction
in place, with a small special case for 4965.

1fa61b2e79 iwlwifi: manage IBSS station properly
Currently iwlwifi will eventually exhaust the station
table when adding the BSSID station for IBSS mode,
unless the interface is set down.

The new mac80211 ibss joined/left notification allows
us to fix that easily by moving the code to add the
IBSS station to the notification, and also adding
code to remove it again when we leave the IBSS.

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.

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

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.

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.

For both 6x00 and 6x50 series devices, periodic Tx IQ calibration is
disabled in uCode, driver do not need to set the periodic Tx/IQ calibration
bit in calibration command.

1933ac4d93 iwlwifi: add wimax/wifi coexist support for 6x50 series
For 6x50 series, it is wimax/wifi combo device, so driver need to enable
the wimax/wifi co-exist function and send the coexist event priority
table to uCode for operation.

The priority table will be used by uCode to determine what is the proper
action it should take when co-exist with WiMAX.
For example, when WiFi runs a scan, it must own radio exclusively, therefore
will disconnect WiMAX if WiMAX is connected.

3f3e0376bb iwlwifi: add SM PS support for 6x50 series
Spatial Multiplexing Power Save was disabled to achieve better
throughput while in power save mode by activating all the rx chains all the time.
By doing so, the device power consumption is high.

Enable static/dynamic spatial multiplexing power save if device support
it, which can lower the power consumption without impact throughput.

a6c5c731c3 iwlagn: invoke L0S workaround for 6000/1000 series
Invoke workaround to avoid instability in L0->L0S->L1 transition on PCIe bus.
Workaround disables L0S state so device moves directly from L0->L1.
Workaround needed on all devices since and including 4965; add to 6000/1000.

Describe bug and workaround better in comments.
