Just some minor conflicts between the wireless-next changes
and Joe Perches's "extern" removal from function prototypes
in header files.
John W. Linville says:
====================
Regarding the Bluetooth bits, Gustavo says:
"The big work here is from Marcel and Johan. They did a lot of work
in the L2CAP, HCI and MGMT layers. The most important ones are the
addition of a new MGMT command to enable/disable LE advertisement
and the introduction of the HCI user channel to allow applications
to get directly and exclusive access to Bluetooth devices."
As to the ath10k bits, Kalle says:
"Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's
just too much to support it. Michal added support for the new firmware
interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are
minor fixes or cleanups."
And also:
"Major changes are:
* throughput improvements including aligning the RX frames correctly and
optimising HTT layer (Michal)
* remove qca98xx hw1.0 support (Bartosz)
* add support for firmware version 999.999.0.636 (Michal)
* firmware htt statistics support (Kalle)
* fix WEP in AP and IBSS mode (Marek)
* fix a mutex unlock balance in debugfs file (Shafi)
And of course there's a lot of smaller fixes and cleanup."
For the wl12xx bits, Luca says:
"Here are some patches intended for 3.13. Eliad is upstreaming a bunch
of patches that have been pending in the internal tree. Mostly bugfixes
and other small improvements."
Along with that...
Arend and friends bring us a batch of brcmfmac updates, Larry Finger
offers some rtlwifi refactoring, and Sujith sends the usual batch of
ath9k updates. As usual, there are a number of other small updates
from a variety of players as well.

It was observed few times, the artificial max_scan limit we
are using mainly to detect FW hangs, can be not enough for
instance while being associated and during heavy traffic.
What we do if the FW won't return with scan results within
the max_time time is a scan abort.
This is especially visible with 10.X fw which in combination
with dual band HW (scanning 32 channels) can end up with
hw_scan close to 10 seconds.

Firmware IE containers can dynamically provide various information what
firmware supports. Also it can embed more than one image so updating firmware
is easy, user just needs to update one file in /lib/firmware/.
The firmware API 2 or higher will use the IE container format, the current API
1 will not use the new format but it still is supported for some time. FW API 2
files are named as firmware-2.bin (which contains both firmware and otp images)
and API 1 files are firmware.bin and otp.bin.

Both firmwares (main and 10.x) have different set of vdev
parameters. To stay in sync with FW API, this patch introduces
a dynamic registering method.
ath10k_wmi_vdev_set_param() takes now indirect u32 value
to identify the Vdev parameter it want's to set.

This is still the only way to submit mgmt frames in case
of 10.X firmware.
This patch introduces wmi_mgmt_tx queue, because of the
fact WMI command can block. This is a problem for
ath10k_tx_htt(), since it's called from atomic context.
The skb queue and worker are introduced to move the mgmt
frame handling out of .tx callback context and not block.

10.X firmware can request a memory pool from host to offload
it's own resources. This is a feature designed especially
for AP mode where the target has to deal with large number
of peers.
So we allocate and map a consistent DMA memory which FW can
use to store e.g. peer rate contol maps.

Since the both firmwares we are going to support,

This is the initial framework to implement dynamic
WMI API in order to support new firmware (from so
called 10.X branch)
The realization is to have a static WMI cmd map for
each of the firmwares, registered upom wmi init.
This patch creates such map for MAIN FW, updates
wmi_cmd_send() calls to take as a parameter
the map value instead of direct WMI enum.
As soon as complete 10.X API will be on place,
we will introduce the FW IE mechanics to dynamicaly
identify which FW is being used and based on that
we will use correct map, API, structures, etc.

The patch removes HTC endpoint tx workers in
favour of direct command submission. This makes a
lot more sense for data path.
mac80211 queues are effectively stopped/woken up
in a more timely fashion preventing build up of
frames. It's possible to push more traffic than
the device/system is able to handle and have no
hiccups or performance degradation with UDP
traffic.
WMI commands will now report errors properly and
possibly block as they actively can wait for tx
credits to become available.

The mgmt_rx event structure has been expanded.
Since the structure header is expanded the payload
(i.e. mgmt frame) is shifted by a few bytes. This
needs to be taken into account in order to support
both old and new firmware.

FW-related ABI/behaviour changes.

Restart the hardware if FW crashes.
If FW crashes during recovery we leave the
hardware in a "wedged" state to avoid recursive
recoveries.
When in "wedged" state userspace may bring
interfaces down (to issue stop()) and then bring
one interface (to issue start()) to reload
hardware manually.

Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.
