Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.

The drivers are converted to use the common firmware header struct.
Because the old header definition failed to indicate that the multi-byte
entries should be little endian, several problems were thus exposed.
These are fixed.

Commit e996db69833a (rtlwifi: rtl8192c: Add init codes for "fw_version"
and "fw_subversion") added initialization for fw_version, but failed to
note that the variable in the firmware header is little-endian. The
following Sparse warning results:
CHECK drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: incorrect type in assignment (different base types)
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: expected unsigned short [unsigned] [usertype] fw_version
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: got restricted __le16 [usertype] version
When fixing this problem, I noticed that several of the drivers contain
nearly identical copies of the firmware header struct, and that only the one
used in rtl8192c{e,u} had correct endian notation. The struct has been
moved into a common header, and the other drivers will be fixed in
subsequant patches.

While working on getting my rtl8821au driver in pretty shape for
inclusion, it is dicosvered that the tm_trigger flag is used only for
the first device using this driver.
This flag handles the thermal power management in the hardware.
To change this add a entry in sttruct rtl_dm, so each device can handle
is separately.

The hardware and firmware for the RTL8192EE utilize a FIFO list of
descriptors. There were some problems with the initial implementation.
The worst of these failed to detect that the FIFO was becoming full,
which led to the device needing to be power cycled. As this condition
is not relevant to most of the devices supported by rtlwifi, a callback
routine was added to detect this situation. This patch implements the
necessary changes in the pci handler, and the linkage into the appropriate
rtl8192ee routine.

Two macros used to copy BSSID information use ether_addr_copy(), thus
the arrays must be 2-byte aligned. In one case, the array could become
unaligned if the struct containing it were changed. Use the __unaligned(2)
attribute to retain the necessary alignment. In addition, the magic number
used to specify the size of the array is replaced by ETH_ALEN.

rtl8821ae: Use common cmd_send_packet
A locking problem was found in routine _rtl92ee_cmd_send_packet() that led

This patch updates the driver to match the latest Realtek release, and
it is an important step in getting the internal code source at Realtek to match

This driver was entered into staging a few cycles ago because there was
not time to integrate the Realtek version into the support routines in
the kernel. Now that there is an effort to converg the code base from Linux
and the Realtek repo, it is time to move this driver. In addition, all the
updates included in the 06/28/2014 version of the Realtek drivers are
included here.
With this change, it will be necessary to delete the staging driver. That
will be handled in a separate patch. As it impacts the staging tree, such a
patch is sent to a different destination.

All of the rtlwifi drivers have an error in the routine that tests if
the data is "special". If it is, the subsequant transmission will be
at the lowest rate to enhance reliability. The 16-bit quantity is
big-endian, but was being extracted in native CPU mode. One of the
effects of this bug is to inhibit association under some conditions
as the TX rate is too high.
Based on suggestions by Joe Perches, the entire routine is rewritten.
One of the local headers contained duplicates of some of the ETH_P_XXX
definitions. These are deleted.

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.

The private array at the end of the rtl_priv struct is not aligned.
On ARM architecture, this causes an alignment trap and is fixed by aligning
that array with __align(sizeof(void *)). That should properly align that
space according to the requirements of all architectures.
