Used NL80211_NUM_ACS to indicate the BCMC fifo used in the driver
which has the same value now, but it is a bad idea relying on that.

When getting a transmit packet from the networking layer simply
enqueue the packet unconditional and have it handled by the dequeue
worker. The transfer of the packet to the bus-specific driver part
is now done from one context.

Apparently HW doesn't require us to generate MMIC
for TKIP suite.
Each frame was 8 bytes longer than it should be
and some APs would drop frames that exceed 1520
bytes of 802.11 payload. This could be observed
during throughput tests or fragmented IP traffic.

The code writes the default_power2 value into the TX field
of the RFCSR50 register, however the condition in the if
statement uses default_power1. Due to this, wrong TX power
value might be written into the register.
Use the correct value in the condition to fix the issue.
Compile tested only.

Ralink 3T chipsets are using a different EEPROM
layout than the others. The EEPROM on these devices
contain more data than the others which does not fit
into 272 byte which the rt2800 driver actually uses.
The Ralink reference driver defines EEPROM_SIZE to
512/1024 bytes for PCI/USB devices respectively.
Increase the EEPROM_SIZE constant to 512 bytes, in
order to make room for EEPROM data of 3T devices.

To improve power consumption in idle associated mode FW may lower
RX power. This low linearity mode is acceptable for listening low rate
RX such as beacons and groupcast. The driver enables LPRX only if PM
is enabled and associated AP's beacon TX rate is 1Mbps or 6Mbps.
LPRX RSSI threshold is used to limit a range where LPRX is applied.

The PCIe code has an array of buffer descriptors (RXBs) that have pages
and DMA mappings attached. In regular use, the array isn't used and the
buffers are either on the hardware receive queue or the rx_free/rx_used
lists for recycling.
Occasionally, during module unload, we'd see a warning from this:
WARNING: at lib/list_debug.c:32 __list_add+0x91/0xa0()
list_add corruption. prev->next should be next (c31c98cc), but was c31c80bc. (prev=c31c80bc).
Pid: 519, comm: rmmod Tainted: G W O 3.4.24-dev #3
Call Trace:

[<fdf2dd7a>] iwl_trans_pcie_free+0x2a/0x90 [iwlwifi]
The reason for this seems to be that in iwl_pcie_rxq_free_rbs() we use
the array to free all buffers (the hardware receive queue isn't in use
any more at this point). The function also adds all buffers to rx_used
because it's also used during initialisation (when no freeing happens.)
This can cause the warning because it may add entries to the list that
are already on it. Luckily, this is harmless because it can only happen
when the entire data structure is freed anyway, since during init both
lists are initialized from scratch.
Disentangle this code and treat init and free separately. During init
we just need to put them onto the list after freeing all buffers (for
switching between 4k/8k buffers); during free no list manipulations
are necessary at all.

In case that an AP/GO interface is started while there is a
station/P2P client associated, need to make sure that the AP/GO
beacon time is far enough from the station's one in oder to allow
the station to receive the DTIM beacons and the following traffic
etc.
To resolve this, when the AP is started, check if there is an
active station interface, and guarantee that the AP/GO TBTT is far
enough from the station one.

As the firmware API has changed significantly and we don't
have support code for the old APIs, bump the version to be
able to release the version 7 API firmware. Unfortunately
this means that the driver in 3.9 and 3.10 can't work, but
that's still better than crashing the device/driver there.

The vring index (MAC queue id) must be set in all TX descriptors
otherwise HW will fail to release descriptors for a specific vring
(disconnect or vring switch flows).
This is normally occurs when fragmentation required, if vring index
will not be the same for all SKB descriptors HW will fail to flush
this MAC queue.

Use common names instead of chip specific ones.
The patch contains no functional changes, but
it makes it easier to add support for further
descriptor sizes.

Different chipsets may use different TXWI descriptor
size. Instead of using a hardcoded value, use the
'queue->winfo_size' which holds the correct value for
a given device.

The current code uses the same index value both
for the channel information array and for the TX
power table. The index starts from 14, however the
index of the TX power table must start from zero.
Fix it, in order to get the correct TX power value
for a given channel.
The changes in rt61pci.c and rt73usb.c are compile
tested only.

Most of these relate to endianness problems, and are purely cosmetic.
But a couple of them were legit -- listen interval parsing and some of
the rate selection code would malfunction on BE systems.
There's still one cosmetic warning remaining, in the (admittedly) ugly
code in cw1200_spi.c. It's there because the hardware needs 16-bit SPI
transfers, but many SPI controllers only operate 8 bits at a time.
If there's a cleaner way of handling this, I'm all ears.

ath_tx_txqaddbuf assumes that all the linked buffers in the queue passed
to it are part of the same A-MPDU or MPDU. The CAB queue rework violates
this assumption, which can cause the internal queue depth to go
negative.
Fix this by increasing the counter for all slots of [bf, bf->bf_lastbf]

This provides some of the same info found in
the ath9k_htc debugfs through the standard ethtool stats API.
This logic is only supported when ath9k_htc debugfs kernel
feature is enabled, since that is the only time stats
are actually gathered.

A number of places treated features wrongly, listing not-supported
