3424a00fd5 rtlwifi: rtl8192c-common: Convert driver to use common DM table initialization
These changes convert both rtl8192ce and rtl8192cu to use the new routine.
Some additional definitions are needed in the core, thus several of the
headers for other drivers are affected, but no other executable code is
changed.

6f8214b690 rtlwifi: Create new routine to initialize the DM tables
Each of the drivers contains a routine that initializes the dm_digtable
member of the driver's private area. As a first step toward reducing the
size of the drivers, a copy of this driver is created in rtlwifi, and the
definitions of the parameters are moved there.

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
the code in the kernel. The primary reason for this is to make it easier for
Realtek to maintain the kernel source without requiring an intermediate like me.

In this process of merging the two source repositories, there are a lot
of changes in both, and this commit is rather large.

e51048cdf0 rtlwifi: avoid accessing RCR directly
The rtl*_set_check_bssid functions are mostly the same, but access the
RCR register in different ways. Use the get_hw_reg abstraction layer
(which reads rtlpci->receive_config for PCI devices and mac->rx_conf for
USB).

There is no functional change for cases where receive_config was
accessed directly. For rtl8192ce, there is still no change because
nothing modifies REG_RCR or receive_config. For rtl8192cu, it now also
applies changes to rx_conf from configure_filter, but that can be
considered a bug which is fixed later.

The routine that processes received frames was returning the RSSI value for the

a result, the strength was the absurd value of 10 dBm. As a result, scans

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.

e1a0c6b3a4 mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40
For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.

To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.

If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.

Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.

While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

f4bda337bb mac80211: support RX_FLAG_MACTIME_END
Allow drivers to indicate their mactime is at RX completion and adjust
for this in mac80211. Also rename the existing RX_FLAG_MACTIME_MPDU to
RX_FLAG_MACTIME_START to clarify its intent. Based on similar code by
Johannes Berg.

aecdc33e11 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking changes from David Miller:

 1) GRE now works over ipv6, from Dmitry Kozlov.

 2) Make SCTP more network namespace aware, from Eric Biederman.

 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.

 4) Make openvswitch network namespace aware, from Pravin B Shelar.

 5) IPV6 NAT implementation, from Patrick McHardy.

 6) Server side support for TCP Fast Open, from Jerry Chu and others.

 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
    Borkmann.

 8) Increate the loopback default MTU to 64K, from Eric Dumazet.

 9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic.  This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail.  Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

36323f817a mac80211: move TX station pointer and restructure TX
Remove the control.sta pointer from ieee80211_tx_info to free up
sufficient space in the TX skb control buffer for the upcoming
Transmit Power Control (TPC).
Instead, the pointer is now on the stack in a new control struct
that is passed as a function parameter to the drivers' tx method.

f1b00f4dab rtlwifi: rtl8192de: Fix phy-based version calculation
Commit d83579e2a5 incorporated some
changes from the vendor driver that made it newly important that the
calculated hardware version correctly include the CHIP_92D bit, as all
of the IS_92D_* macros were changed to depend on it.  However, this bit
was being unset for dual-mac, dual-phy devices.  The vendor driver
behavior was modified to not do this, but unfortunately this change was
not picked up along with the others.  This caused scanning in the 2.4GHz
band to be broken, and possibly other bugs as well.

This patch brings the version calculation logic in parity with the
vendor driver in this regard, and in doing so fixes the regression.
However, the version calculation code in general continues to be largely
incoherent and messy, and needs to be cleaned up.

2c208890c6 wireless: Remove casts to same type
Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;
@@

-       (T *)p
+       p

Neatened the mwifiex_deauthenticate_infra function which
was doing odd things with array pointers and not using
is_zero_ether_addr.
