Instead of waiting for IFF_UP of the primary net device to determine
the band and channel information of the wiphy structure, this is now
done during driver initialization in brcmf_cfg80211_attach(). The
channel information is obtained from the device and the 2G band is
updated when 40MHz bandwidth is enabled for that band. Before this
change the band and channel objects were common between multiple
brcmfmac devices in the system, which make that information rather
unreliable. That is also fixed with this reworked implementation.

Reworked the debugfs functions in the driver making it easier for
other driver parts to add a debugfs entry and keeping the information
they want to expose in debugfs private, ie. not in a header.
This is accomplished by providing the function brcmf_debugfs_add_entry()
in which the caller provides a read function in which they provide the
content. The debugfs function will take care of creating the debugfs
entry and cleaning up upon removal.

Applying ++ to a bool is equivalent to setting it true, regardless of
its initial value (bools are not uint1_t). Hence the function
wl_get_vif_state_all can only ever return true/false. The only in-tree
caller uses its return value as a boolean. So update its return type,
and since the list traversal and bit testing have no side effects,
just return true immediately. Its return value tells if any vif is in
the specified state, so also rename it to brcmf_get_vif_state_any.

FWS is always queuing frames and using a worker for de-queueing,
this is not always efficient for all bus layer. For example SDIO
has an internal queue and worker making the queueing of FWS
unnecessary. Make it possible to bypass the worker if fws mode
is none using a bus interface configuration. For USB bus layer
this configuration is set true to have fws provide queueing
regardless the fws mode.

When a BSS provides both 2.4GHz and 5GHz bands, in many cases it
makes sense to choose 5GHz. Typically a 5GHz channel is less crowded
and has less interference and therefore its performance will be
better than a crowded 2.4 GHz channel. This patch configures
'join_pref' to induce firmware to preferably select 5GHz BSS.

brcmfmac has been broken on my cubietruck with a BCM43362:

brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0:
Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d
since commit 5303626103: "brcmfmac: update core reset and disable routines".
The problem is that since this commit brcmf_chip_ai_resetcore no longer sets
BCMA_IOCTL itself before bringing the core out of reset, instead relying on
brcmf_chip_ai_coredisable to do so. But brcmf_chip_ai_coredisable is a nop
of the chip is already in reset. This patch modifies brcmf_chip_ai_coredisable
to always set BCMA_IOCTL even if the core is already in reset.
This fixes brcmfmac hanging in firmware loading on my board.

When receiving an IBSS_JOINED event select the BSS object
based on the {bssid, channel} couple rather than the bssid
only.
With the current approach if another cell having the same
BSSID (but using a different channel) exists then cfg80211
picks up the wrong BSS object.
The result is a mismatching channel configuration between
cfg80211 and the driver, that can lead to any sort of
problem.
The issue can be triggered by having an IBSS sitting on
given channel and then asking the driver to create a new
cell using the same BSSID but with a different frequency.
By passing the channel to cfg80211_get_bss() we can solve
this ambiguity and retrieve/create the correct BSS object.
All the users of cfg80211_ibss_joined() have been changed
accordingly.
Moreover WARN when cfg80211_ibss_joined() gets a NULL
channel as argument and remove a bogus call of the same
function in ath6kl (it does not make sense to call
cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

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.

The driver uses platform_driver_probe() to obtain platform data
if any. However, that function is placed in the .init section so
it must be called upon driver module initialization.
The problem was reported by Fenguang Wu resulting in a kernel
oops because the .init section was already freed.

There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

The kernel configuration for the driver could result in
compilation issues as reported by Randy Dunlap. His results
are show below:
"on x86_64:
when
CONFIG_MMC=m
CONFIG_BRCMUTIL=y
CONFIG_BRCMFMAC=y
CONFIG_BRCMFMAC_SDIO=y
This bool kconfig symbol:
config BRCMFMAC_SDIO
bool "SDIO bus interface support for FullMAC driver"
depends on MMC
allows BRCMFMAC_SDIO to be y even when MMC=m.
Is there a reasonable solution to this?
This causes many build errors:
drivers/built-in.o: In function `brcmf_sdio_assert_info':
dhd_sdio.c:(.text+0x39609b): undefined reference to `sdio_claim_host'

The gain level control for the test tone has been changed. This
calbration test tone is used to determine the i/q compensation.
The i/q calibration routine has been reworked to accomodate this.

For debug purposes it is good to have the phy and radio information
available in the log. Only logged when driver is built when BRCMDBG
or BRCM_TRACING kconfig are set.

The function wlc_lcnphy_load_tx_gain_table() has a target PA
gain specified for the iPA variant of the bcm4313. This gain
value is reduced to avoid PA distortion. The if-statement is
removed because it was rather redundant in the first place.
Please note that this patch does not provide full iPA support.
