commit (3be8fbab tuntap: fix error return code in tun_set_iff()) breaks the
creation of multiqueue tuntap since it forbids to create more than one queues
for a multiqueue tuntap device. We need return 0 instead -EBUSY here since we
don't want to re-initialize the device when one or more queues has been already
attached. Add a comment and correct the return value to zero.

The sockaddr_nfc_llcp struct has as hole between ->sa_family and
->dev_idx so I've added a memset() to clear it and prevent an
information leak.
Also the ->nfc_protocol element wasn't set so I've added that.
"uaddr->sa_family" and "llcp_addr->sa_family" are the same thing but
it's less confusing to use llcp_addr consistently throughout.

An early draft of the PHC patch series included an alarm in the
gianfar driver. During the review process, the alarm code was dropped,
but the capability removal was overlooked. This patch fixes the issue
by advertising zero alarms.
This patch should be applied to every 3.x stable kernel.

efx_mcdi_get_board_cfg() uses a buffer for the firmware response that
is only large enough to hold subtypes for the originally defined set
of NVRAM partitions. Longer responses are truncated, and we may read
off the end of the buffer when copying out subtypes for additional
partitions. In particular, this can result in the MTD partition for
an FPGA bitfile being named e.g. 'eth5 sfc_fpga:00' when it should be
'eth5 sfc_fpga:01'. This means the firmware update tool (sfupdate)
can't tell which bitfile should be written to the partition.
Correct the response buffer size.

Unicast packet might be of type either UNICAST or
UNICAST4ADDR.
In the two cases the header size is different, but the
mechanism checking the TTVN field was assuming it to be
always of the same type (UNICAST), so failing to access the
inner Ethernet header in case of UNICAST4ADDR.
Fix this by passing the real header length as argument.

BE3 HW in UMC mode could wrongly double tag a packet with PVID
when the packet already has a inlined VLAN tag.
In UMC mode, When HW finds that a packet is already VLAN tagged
PVID should not be inserted into the packet.
To fix this use the FW hack to instruct the HW to skip PVID tagging.

The ASIC could lockup in the transmit path when it tries
to insert VLAN in a specific ipv6 packet.
1) Identify the packet which can cause this.
2) Check if the firmware provides a workaround to prevent this.
3) If workaround is not present, drop the packet.
4) If the firmware provides a workaround, insert the VLAN tag in the
packet and inform the firmware to skip further VLAN insertions.

To work-around a HW bug that corrupts certain packets while inserting

====================
A few more stragglers intended for 3.10...
For the Bluetooth bits, Gustavo says:
"A few more patches intended for 3.10, the most important one is the support in
btusb for fw loading for the Intel Bluetooth device. Other than that we have
only fixes and clean ups."
For the iwlwifi bits, Johannes says:
"Here are a few more changes for the 3.10 stream, some bugfixes,
adjustments to some powersave parameters and a new device ID."
For the NFC bits, Samuel says:
"This pull request includes Marcel's Kconfig dependency fix on top of the LLCP
code move to net/nfc."
On top of that...Yogesh Ashok Powar provides a few PCI-related mwifiex
updates, Hauke Mehrtens provides a small ssb feature for spurious
tone avoidance on a specific chip, and Larry Finger provides a small
rtlwifi fix related to avoiding false detection of AP loss.

Samuel Ortiz <sameo@linux.intel.com> says:
"With this one we have:
- One patch for moving the LLCP code into net/nfc.
It fixes a build annoyance reported by Dave Miller caused by the fact
that the LLCP code object targets are not in the same directory as the
Makefile trying to build them is. It prevents us from doing e.g.
make net/nfc/llcp/sock.o
Moving the LLCP code into net/nfc and not making it optional anymore
makes sense as LLCP is a fundamental piece of the NFC specifications
and thus should be in the core NFC directory.
- One patch that fixes the missing dependency against RFKILL. Without it NFC
fails to properly build when it's builtin and CONFIG_RFKILL=m."

Since the NFC subsystem gained RFKILL support, it needs to be able

Make power management in MVM driver enabled by default and
remove using the power_save module parameter. Rely only on
the power_scheme parameter to decide if power management
should be used.

Recently in low power (LP) mode FW moved from active to power save mode
after TX/RX completion faster than in balanced power mode (BPS).
Change AM-to-PSM transition time so that it will be the same as for BPS.

first_antenna is supposed to return the first antenna as a
0-based bitmap: ANT_A is BIT(0), ANT_B is BIT(1), etc...
Since ffs is 1 based (ffs(BIT(0)) = 1), then we had an
off-by-one bug:
BIT(ffs(ANT_A)) = BIT(ffs(BIT(0))) = BIT(1) = ANT_B.
So what we really want is:
BIT(ffs(ANT_A) - 1) = BIT(ffs(BIT(0)) - 1) = BIT(0) = ANT_A.

FW does the synchronization of the different modules during init.
It will report different modules, that it is ready at different times.
The fw download 'winner' will be reported fw ready first. Without this
patch, btmrvl was already continuing before the FW told it too. Probably
on behalf of the 'winner' which then never sees FW ready and times out.

The Bluetooth Core Specification (4.0) defines the Write LE Host
Supported HCI command as only available for controllers supporting
BR/EDR. This is further reflected in the Read Local Extended Features
HCI command also not being available for LE-only controllers. In other
words, host-side LE support is implicit for single-mode LE controllers
and doesn't have explicit HCI-level enablement.
This patch ensures that the LE setting is always exposed as enabled
through mgmt and returns a "rejected" response if user space tries to
toggle the setting. The patch also ensures that Write LE Host Supported
is never sent for LE-only controllers.

All HCI command send functions that take a pointer to the command
parameters do not need to modify the content in any way (they merely
copy the data to an skb). Therefore, the parameter type should be
declared const. This also allows passing already const parameters to
these APIs which previously would have generated a compiler warning.
