8b5c7f6c2b wil6210: fix timeout for start_pcp
It may take up to 3500ms for the FW to start AP/PCP. Increase accordingly,
adding some safety margin.

59505c02e1 ath9k: limit multicast buffer hardware queue depth
The CAB (Content after Beacon) queue is used for beacon-triggered
transmission of buffered multicast frames. If lots of multicast frames
were buffered and this queue fills up, it drowns out all regular
traffic. To limit the damage that buffered traffic can do, try to limit
the queued data to becaon_interval / 8.

ee06fcad74 brcmfmac: free primary net_device when brcmf_bus_start() fails
When initialization within brcmf_bus_start() fails on steps
before the brcmf_net_attach() the net_device for the primary
interface needs to be freed.

This patch resolves a panic during kernel boot as reported
by Stephen Warren.

25bf6ce41d rt2x00: add queue_init callback to rt2x00_ops
The driver uses static data structures for initializing
specific fields of a given data queue. These static
queue data descriptor structures are containing values
which related to a given chipset.

Even though the values are chip specific, the actual
selection of the used structure is based on device
specific vendor/product identifiers. This approach works,
but it is not always reliable. Sometimes the vendor and/or
device IDs of the PCI and USB devices contains improper
values which makes it impossible to select the correct
structure for such devices.

The patch adds a new callback to tr2x00_ops which
is called after the chipset detection is finished.
This allows the drivers to do dynamic initialization
of the data_queue structure for a given queue based
on the actual chipset.

After each driver implements the queue_init callback,
the data_queue_desc structure will be removed.

568f7a438f rt2x00: rt2x00queue: add priv_size field to struct data_queue
Add a new field into struct data_queue and store
the size of the per-queue_entry private data in
that. Additionally, use the new field in the
rt2x00queue_alloc_entries function to compute
the size of the queue entries for a given queue.

The patch does not change the current behaviour
but makes it possible to remove the queue_desc
parameter of the rt2x00queue_alloc_entries function.
That will be done by a subsequent patch.

50a0f5bc30 ath9k: Remove redundant code
The phy error mask registers are programmed already
in ath9k_ani_restart(), so there is no need to set them
in ath9k_ani_reset().

ff23e0845b ath9k: Fix ofdm weak signal configuration
The commit, "ath9k_hw: improve ANI processing and rx desensitizing parameters"
removed code setting various phy registers holding threshold values.

This is likely required for OFDM weak signal detection to function
correctly, so add them, but skip AR9462 and AR9565.

b99553fb60 ath9k: Fix ANI levels
The commit, "ath9k_hw: improve ANI processing and rx desensitizing parameters"
modified the immunity level tables for both CCK and OFDM. Fix them
so that the tables are in sync with the internal driver/codebase.

a04eb985f1 ath9k: Fix ANI monitoring
The commit "ath9k_hw: improve ANI processing and rx desensitizing parameters"
changed various ANI operational parameters to address a specific
card/environment. This is not really applicable for other cards
in general usage.

As per internal documentation, lowering the immunity level can be
done only after 5 periods have passed and the CCK/OFDM errors are
below the low watermak threshold - which have been fixed at 300 and
400 respectively by the sytems team.

Raising the immunity level can be done when CCK/OFDM errors exceed
600 and 1000 (per second).

Set these values once during attach.

80b4205bc1 ath9k: Fix OFDM weak signal detection for AP mode
The commit "ath9k_hw: improve ANI processing and rx desensitizing parameters"
changed the OFDM weak signal detection logic to disable it
for AP mode, which is not allowed. Fix this and enable it always
for AP mode.
