The patch splits cfg80211_check_combinations()
into an iterator function and a simple iteration
user.
This makes it possible for drivers to asses how
many channels can use given iftype setup. This in
turn can be used for future
multi-interface/multi-channel channel switching.

At some locations, channels 149-165 are considered a single
bundle, while at some other locations, e.g., Indonesia, channels
149-161 are considered a single bundle, while channel 165 belongs
to a different bundle. This means that:
1. A station interface connection to an AP on channel 165 allows
the instantiation of a P2P GO on channels 149-165.
2. A station interface connection to an AP on channels 149-161
does NOT allow the instantiation of a P2P GO on channel 165.
Fix this.

When we're performing reauthentication (in order to elevate the
security level from an unauthenticated key to an authenticated one) we
do not need to issue any encryption command once authentication
completes. Since the trigger for the encryption HCI command is the
ENCRYPT_PEND flag this flag should not be set in this scenario.
Instead, the REAUTH_PEND flag takes care of all necessary steps for
reauthentication.

Commit 1c2e004183178 introduced an event handler for the encryption key
refresh complete event with the intent of fixing some LE/SMP cases.
However, this event is shared with BR/EDR and there we actually want to
act only on the auth_complete event (which comes after the key refresh).
If we do not do this we may trigger an L2CAP Connect Request too early
and cause the remote side to return a security block error.

This reverts commit d2bee8fb6e18f6116aada39851918473761f7ab1.
Enabling autosuspend for Intel Bluetooth devices has been shown to not
work reliable. It does work for some people with certain combinations
of USB host controllers, but for others it puts the device to sleep and
it will not wake up for any event.
These events can be important ones like HCI Inquiry Complete or HCI
Connection Request. The events will arrive as soon as you poke the
device with a new command, but that is not something we can do in
these cases.
Initially there were patches to the xHCI USB controller that fixed
this for some people, but not for all. This could be well a problem
somewhere in the USB subsystem or in the USB host controllers or
just plain a hardware issue somewhere. At this moment we just do
not know and the only safe action is to revert this patch.

brcmfmac has been broken on my cubietruck with a BCM43362:
brcmfmac: brcmf_chip_recognition: found AXI chip: BCM43362, rev=1
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 53036261033: "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.

Sometimes, due to the race between Rx path and WMI_BA_STATUS_EVENTID WMI event,
few frames may be passed to the stack before reorder buffer allocated.
Then, after BACK establishment, it start getting frames with sequence number ahead of
SSN, and it get interpreted as missing frames. Then, BACK mechanism will wait
for missing frames; data traffic will be stopped. In case of interface configured
for DHCP, this data delay causes DHCP failure.
Relax checking for sequence number; use sequence of 1-st frame handled by the buffer
as SSN for this buffer.
This is work-around, real fix should be done when proper BACK mechanism implemented.

HW should never attempt to perform DMA for unused queues.
For rtl8187se this is ensured by setting a dedicated register at
init time, before enabling TX.
In rtl8180/5 the register is only written at the first TX (because
in rtl8180/5 it serves also to kick DMA for used queues).
This should be enough, but it's worth to add a register write at
init time, before enabling TX.

Currently this have no functional impact because the high-priority

This patch removes high-priority queue bits and it adds the
