In case of QoS packets the packet payload isn't aligned to
4 bytes. In that case the mac80211 layer take care of that
via memmove() in ieee80211_deliver_skb().
Add support of copy packets from aggregation buffer to the
skbs with packet payload aligned care. In case of QoS packets
copy the packets in offset of 2 bytes guarantee payload aligned
to 4 bytes.

A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).
There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
path.
Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.
A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.

When resuming (after wowlan), we want the rx packets (which is
usually the wake-up packet itself) to be passed to mac80211 only
after the resume notifier was completed, and mac80211 is up and
running (otherwise, the packets will be dropped).
By enqueueing the netstack_work to a freezable workqueue, we can
guarantee the rx processing to occur only after mac80211 was resumed.

When rx_streaming.interval is non-zero, use automatic rx streaming.
Enable rx streaming on the each rx/tx packet, and disable it
rx_streaming.duration msecs later.
When rx_streaming.always=0 (default), rx streaming is enabled only
when there is a coex operation.

The rx-status passed to mac80211 along with each received frame contains the
band on which the frame was received. Under certain circumstances, this band
information may be incorrect, causing in worst case a WARNING from mac80211,
and causes the received frame to be dropped.
This scenario mainly occurs when performing connected-mode scans, when the
received scan results are from the other band than the one currently
associated to.

To achieve maximal throughput, it is very important to react to
interrupts as soon as possible. Currently the interrupt handler wakes up
a worker for handling interrupts in process context. A cleaner and more
efficient design would be to request a threaded interrupt handler. This
handler's priority is very high, and can do blocking operations such as
SDIO/SPI transactions.
Some work can be deferred, mostly calls to mac80211 APIs
(ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a
different worker, we can keep the irq handler thread more I/O
responsive. In addition, on multi-core systems the two threads can be
scheduled on different cores, which will improve overall performance.
The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was
changed. For simplicity, always query the FW for more pending
interrupts. Since there are relatively long bursts of interrupts, the
extra FW status read overhead is negligible. In addition, this enables
registering the IRQ handler with the ONESHOT option.

On newer hardware revisions, there is no need to write the host's
counter at the end of a RX transaction. The same applies to writing the
number of packets at the end of a TX transaction.
It is generally a good idea to avoid unnecessary SDIO/SPI transfers.
Throughput and CPU usage are improved when avoiding these.
Send the host's RX counter and the TX packet count only if needed, based
on the hardware revision.

for debugging purposes, wl12xx determines whether a rx packet
is a beacon packet.
however, it checks only the frame_control subtype without checking
the actual packet type, which leads to false identification in some
cases.

This patch adds support for the new wl12xx firmware (Rev 6.1.3.50.49)
Since this fw is not backward compatible with previous fw versions,
a new fw (with different name) is being fetched.
(the patch is big because it contains all the required fw api changes.
splitting it into multiple patches will result in corrupted intermediate
commits)

Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
channel numbers in the 2GHz and 5GHz band we can't map from channel to
frequency without knowing the band. This is no problem as in most contexts we
know the band. In places where we don't know the band (and WEXT compatibility)
we assume the 2GHz band for channels below 14.
This patch does not implement all channel to frequency mappings defined in
802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
channels as well as 802.11y channels have been omitted.
The following drivers have been updated to reflect the API changes:

Rework cmd and acx interfaces, it was just too confusing earlier. Now
all commands need to contain all the needed headers, either just cmd
headers or both cmd and acx headers. This accomplish to remove the
extra copy done for each command. The interfaces are now properly
documented as well.
Also try to make all commands safe for DMA transfers. I might have missed
some, but most of them should be fixed now.
And this is not all! As a free bonus you will also get some cosmetic
cleanups and code reorganisation. Order today!

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:
