We used to free all the Tx queues memory when interface is brought
down and reallocate them again in interface up. This requires
order-4 allocation for txq->cmd[]. In situations like s2ram, this
usually leads to allocation failure in the memory subsystem. The
patch fixed this problem by allocating the Tx queues memory only at
the first time. Later iwl_down/iwl_up only initialize but don't
free and reallocate them. The memory is freed at the device removal
time. BTW, we have already done this for the Rx queue.

When collecting tx data for non-aggregation packets in rate scaling, if
the tx data matches "other table", it still uses current table to update
the stats and calculate average throughput in function rs_collect_tx_data().
This can mess up the rate scaling data structure and cause a kernel panic
in a BUG_ON statement in rs_rate_scale_perform().
To fix this bug, we pass table pointer instead of window pointer (pointed
to by table pointer) to function rs_collect_tx_data() so that the table
being used is consistent.

While ar9170's USB transport packet size is currently set to 8KiB,
the PHY is capable of receiving AMPDUs with up to 64KiB.
Such a large frame will be split over several rx URBs and
exceed the previously allocated space for rx stream reconstruction.
This patch increases the buffer size to 64KiB which is
in fact the phy & rx stream designed size limit.

If the hardware generates unattended interrupts, driver will not ack them,
defeating the interrupt coalescing feature. This results in high number
of interrupts per second and high CPU utilization.
This patch addresses this issue by acking those unattended interrupts
in the tasklet. Local test showed an order of magnitude improvement
in terms of the number of interrupts without sacrificing networking

Noisefloor calibration involves querying hardware for samples
and storing this information on a history buffer in hardware for
actual noisefloor calibration processing in hardware. The history
buffer supports collecting information for all Atheros hardware,
one history buffer slot for each chain on each channel used for
MIMO operation. For current hardware this means one history
buffer slot for each chain on both the control (or primary) channel
and the extension (or secondary) channel. We know which noisefloor
registers to poke for collecting noisefloor data through the
chainmask.
For AR9285 and AR9271 devices, both 1x1, the chaimmask is defined as
0x9 = 0b0001001. The first four bits represent each chain out of
a maximum of 4 chains [0-3] on the primary channel. The last four
bits represent each chain on the extension channel. A chainmask
of 0x9 therefore indicates chain 1 is active on both the primary
and the extension channel.
AR9271 only requires collecting and storing noisefloor history buffer
data for the first chain on both the control and extension channel
(nfarray[0] and nfarray[3]) so fix the code and avoid which reads
and writes to the history buffer for the other chains.
Since the noisefloor varies depending on the number of chains your
device supports also initialize the noisefloor history buffer with
reasonable values seen on 1x1 devices such as AR9285.

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.

Monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the
expected_ack_count also drops. At the same time, the aggregated
ba_timeout (the number of ba timeout retries) also rises. If the
actual_ack_count/expected_ack_count ratio is 0 and the number of ba
timeout retries rises to BA_TIMEOUT_MAX, no tx packets can be delivered.

mac80211 recently implemented two new callbacks that are used to request
station add/remove from the driver. The benefot from these new callbacks
are that they enable the driver to sleep while performing this work.
This is a big patch since a few things need to be coordinated in this move.
First we need to decouple station management from rate scaling, which
caused a lot of code to be moved and/or deleted. Next we needed to tie in
with mac80211's station management callback and let it direct our station
management as well as trigger the rate scaling initialization.
Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
Currently the broadcast station is added after every RXON command. Change
this to only add the broadcast station when interface is added by mac80211.
With this we need some extra work to ensure broadcast station is always
present since station table is cleared when RXON without ASSOC bit set is
sent. To deal with this we re-add all driver known stations to uCode after
such an RXON command is sent.
We also do some cleanup and remove the various calls to clear the station
table. We now only clear the station table in two scenarios:
- only clear uCode portion of station table when RXON command without ASSOC
bit is sent
- clear uCode and driver portion when interface goes down or is removed.
We need to do this clearing when interface goes down to deal with the
device restart/reconfigure routines which do not remove the interface, but
do add the interface during reconfiguration.
Previously the keys were also cleared when station table in driver is
cleared, this is not done anymore since mac80211 will take care that keys
are set and cleared correctly.
There is a known issue with this change. Associating with different AP
without bringing interface down fails with a firmware error. This is
because of the lack of full station notification support and the later
patches in this series that complete the station notification support will
fix this.

FH register dump debug feature was recently added for 5000 and later;
4965 can use it also.

Commit a239a8b47c introduced a
noisy message, that fills up the log very fast.
The error seems not to be fatal (the connection is stable and
performance is ok), so make it IWL_DEBUG_TX rather than IWL_ERR.
