Please pull this batch of updates intended for the 3.17 stream...

This is primarily a Bluetooth pull.  Gustavo says:

"A lot of patches to 3.17. The bulk of changes here are for LE support.
The 6loWPAN over Bluetooth now has it own module, we also have support for
background auto-connection and passive scanning, Bluetooth device address
provisioning, support for reading Bluetooth clock values and LE connection
parameters plus many many fixes."

The balance is just a pull of the wireless.git tree, to avoid some
pending merge problems.

This patch introduces a possibility for userspace to set various (so far
two) modes of generating addresses. This is useful for example for
NetworkManager because it can set the mode to NONE and take care of link
local addresses itself. That allow it to have the interface up,
monitoring carrier but still don't have any addresses on it.

One more use-case by Dan Williams:
<quote>
WWAN devices often have their LL address provided by the firmware of the
device, which sometimes refuses to respond to incorrect LL addresses
when doing DHCPv6 or IPv6 ND.  The kernel cannot generate the correct LL
address for two reasons:

1) WWAN pseudo-ethernet interfaces often construct a fake MAC address,
or read a meaningless MAC address from the firmware.  Thus the EUI64 and
the IPv6LL address the kernel assigns will be wrong.  The real LL
address is often retrieved from the firmware with AT or proprietary
commands.

2) WWAN PPP interfaces receive their LL address from IPV6CP, not from
kernel assignments.  Only after IPV6CP has completed do we know the LL
address of the PPP interface and its peer.  But the kernel has already
assigned an incorrect LL address to the interface.

So being able to suppress the kernel LL address generation and assign
the one retrieved from the firmware is less complicated and more robust.

Network driver for Armada 375 SoC

This is the fourth round of the Armada 375 network support patchset. I've
tried to address all the feedback provided for last version and I hope the
driver looks better now.

If there's nothing else to fix, we'd like to merge this for v3.17. The first
patch should go through the network tree, and the other patches through
the mvebu tree.

Thanks a lot for all the great review, and feel free to comment some more!

Changes from v3:

  * Further optimization of the MTU, MAC and ring parameter change to make
    it smoothier.

  * Lots of cleanups in the parser configuration code, most of them addressing
    the feedback from Francois. This include fixing: missing curly braces,
    excessive parenthesis, excessive scope, and making several functions
    more readable.

  * Removed the Rx/Tx queue number module parameter. There's no reason to
    use any other than the default hardware-defined value.

Changes from v2:

  * Reworked mvpp2_prs_tcam_first_free() as suggested by Joe and Francois,
    to have a single loop instead of two.

  * Replaced mvpp2_cpu_interrupts_enable/disable(pp, cpu) with one function
    that enables/disable interrupts on all the CPUs at once.

  * Factor out Tx descriptor DMA unmap + descriptor put sequence to have
    more readable code, as suggested by Francois.

  * Remove redundant netif_running() checks in the ingress and egress path,
    as suggested by Francois.

  * Reworked ring parameter, MTU and MAC address setting to produce a
    more gentle modification of the parameter, and have a fallback in the
    event of a failure.

  * Fixed a percpu memory leak on error path, also noted by Francois.

  * Removed the usage of the legacy net_device irq field, requested by
    Francois.

  * Removed the unneeded multiple Tx port support. It was hardcoded to a single
    Tx port in the previous version so we decided to drop it and simplify the
    code.

  * Optimize the on_each_cpu() calls to clear the sent counters and the
    TX_DONE pkts coalescing setting. on_each_cpu is expensive so it's better
    to minize the calls to it.

Changes from v1:

  * Marcin Wojtas is the author of the driver, so I fixed authorship
    for patch 1/3:
    "ethernet: Add new driver for Marvell Armada 375 network unit"

This patchset adds a new network driver to support the network controller
in Armada 375 SoC.

The network interfaces share a common hardware unit called Packet Processor,
which contains a common register space and per-port register spaces.

The new network unit has different RXQ and TXQ management. The ports
associate so-called per-port "logical queues" which are mapped to "physical
queues". The latter are shared among the ports.

Fo the egress part, the mapping for each port is predefined by hardware.
The egress path incorporates so-called aggregation queues (one per CPU),
from where the data is passed to the physical queues and then via prefetch
buffer to the TxDMA.

The ingress path has a Parser and Classifier (PnC) and a Buffer Manager (BM)
whose usage is obligatory. We are only implementing a simple configuration
for the Parser and Classifier, yet the code is considerably large.

This network unit has other optional features like xPON, WoL, Hardware
Forwarding, and more. This initial commit doesn't provide support for these.

The mvpp2 network driver has been written by Marcin Wojtas and then reviewed
and cleaned up by Ezequiel Garcia.
