====================
This pull request is intended for the 3.8 stream.  It is a bit large
-- I guess Thanksgiving got me off track!  At least the code got to
spend some time in linux-next... :-)

This includes the usual batch of pulls for Bluetooth, NFC, and mac80211
as well as iwlwifi.  Also here is an ath6kl pull, and a new driver
in the rtlwifi family.  The brcmfmac, brcmsmac, ath9k, and mwl8k get
their usual levels of attention, and a handful of other updates tag
along as well.

For more detail on the pulls, please see below...

On Bluetooth, Gustavo says:

"Another set of patches for integration in wireless-next. There are two big set
of changes in it: Andrei Emeltchenko and Mat Martineau added more patches
towards a full Bluetooth High Speed support and Johan Hedberg improve the
single mode support for Bluetooth dongles. Apart from that we have small fixes
and improvements."

...and:

"A few patches to 3.8. The majority of the work here is from Andrei on the High
Speed support. Other than that Johan added support for setting LE advertising
data. The rest are fixes and clean ups and small improvements like support for
a new broadcom hardware."

On mac80211, Johannes says:

"This is for mac80211, for -next (3.8). Plenty of changes, as you can see
below. Some fixes for previous changes like the export.h include, the
beacon listener fix from Ben Greear, etc. Overall, no exciting new
features, though hwsim does gain channel context support for people to
try it out and look at."

...and...:

"This one contains the mac80211-next material. Apart from a few small new
features and cleanups I have two fixes for the channel context code. The
RX_END timestamp support will probably be reworked again as Simon Barber
noted the calculations weren't really valid, but the discussions there
are still going on and it's better than what we had before."

...and:

"Please pull (see below) to get the following changes:
 * a fix & a debug aid in IBSS from Antonio,
 * mesh cleanups from Marco,
 * a few bugfixes for some of my previous patches from Arend and myself,
 * and the big initial VHT support patchset"

And on iwlwifi, Johannes says:

"In addition to the previous four patches that I'm not resending,
we have a number of cleanups, message reduction, firmware error
handling improvements (yes yes... we need to fix them instead)
and various other small things all over."

...and:

"In his quest to try to understand the current iwlwifi problems (like
stuck queues etc.) Emmanuel has first cleaned up the PCIe code, I'm
including his changes in this pull request. Other than that I only have
a small cleanup from Sachin Kamat to remove a duplicate include and a
bugfix to turn off MFP if software crypto is enabled, but this isn't
really interesting as MFP isn't supported right now anyway."

On NFC, Samuel says:

"With this one we have:

- A few HCI improvements in preparation for an upcoming HCI chipset support.
- A pn544 code cleanup after the old driver was removed.
- An LLCP improvement for notifying user space when one peer stops ACKing I
  frames."

On ath6kl, Kalle says:

"Major changes this time are firmware recover support to gracefully
handle if firmware crashes, support for changing regulatory domain and
support for new ar6004 hardware revision 1.4. Otherwise there are just
smaller fixes or cleanups from different people."

Thats about it... :-)  Please let me know if there are problems!

This patch reports the change made by Stephen Hemminger in ipip and gre[6] in
commit eccc1bb8 (tunnel: drop packet if ECN present with not-ECT).

Goal is to handle RFC6040, Section 4.2:

Default Tunnel Egress Behaviour.
 o If the inner ECN field is Not-ECT, the decapsulator MUST NOT
      propagate any other ECN codepoint onwards.  This is because the
      inner Not-ECT marking is set by transports that rely on dropped
      packets as an indication of congestion and would not understand or
      respond to any other ECN codepoint [RFC4774].  Specifically:

      *  If the inner ECN field is Not-ECT and the outer ECN field is
         CE, the decapsulator MUST drop the packet.

      *  If the inner ECN field is Not-ECT and the outer ECN field is
         Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the
         outgoing packet with the ECN field cleared to Not-ECT.

The patch takes benefits from common function added in net/inet_ecn.h.

Like it was done for Xin4 tunnels, it adds logging to allow detecting broken
systems that set ECN bits incorrectly when tunneling (or an intermediate
router might be changing the header). Errors are also tracked via
rx_frame_error.

On BE2 chip, an interrupt may be raised even when EQ is in un-armed state.
As a result be_intx()::events_get() and be_poll:events_get() can race and
notify an EQ wrongly.

Fix this by counting events only in be_poll(). Commit 0b545a62 fixes
the same issue in the MSI-x path.

But, on Lancer, INTx can be de-asserted only by notifying num evts. This
is not an issue as the above BE2 behavior doesn't exist/has never been
seen on Lancer.

If all slaves of a balance-rr bond with ARP monitor are enslaved
with down link state, bond keeps down state even after slaves
go up.

This is caused by bond_enslave() setting curr_active_slave to
first slave not taking into account its link state. As
bond_loadbalance_arp_mon() uses curr_active_slave to identify
whether slave's down->up transition should update bond's link
state, bond stays down even if slaves are up (until first slave
goes from up to down at least once).

Before commit f31c7937 "bonding: start slaves with link down for
ARP monitor", this was masked by slaves always starting in UP
state with ARP monitor (and MII monitor not relying on
curr_active_slave being NULL if there is no slave up).

following two benefits: 1) QFQ+ is faster than QFQ, 2) differently
from QFQ, QFQ+ correctly schedules also non-leaves classes in a
hierarchical setting. A detailed description of QFQ+, plus a
performance comparison with DRR and QFQ, can be found in [1].

This patch adds support for USB dynamic autosuspend to the

device but enables power savings in upstream hosts and
the host CPU.

Note currently Linux doesn't automatically enable this
functionality by default for devices so to test this:

Taking PHY lock is not required on some older designs, but we are removing this
complication and always taking it since it is always required on newer designs
and does not worth the code complication on the older boards.

Taking PHY lock was initially required only on specific boards which had their
MDC/MDIO bus crossed, but since this lock is now always required, for example,
when NCSI is present, the PHY lock will always be taken.

Per measurements, the SFP+ suffered from small current leakage in two cases:
 - When no module was plugged and TX laser was disabled. The fix was to enable
   it, and when module is plugged in, check if it needs to be disabled.
 - When over-current event occurs due to invalid SFP+ module, the HW basically
   shuts down the current for this module, but the SW needs to complete this
   by issuing a power down via a GPIO.

When drivers works on top of an old bootcode, it is theoretically subjected to
MDC/MDIO failures since the MDIO clock is set in the beginning of each sequence,
rather than per CL45 command. On rare cases an old bootcodes may change that in
the middle, so to address that, the MDIO clock is set for each CL45 access.
In addition, setting the MDIO clock is now done per EMAC base, and
not per port number, since a specific port can potentially use both EMACs for
different PHY accesses.
