====================
Here is one more pull request for the 3.13 window.  This is primarily
composed of downstream pull requests that were posted while I was
traveling during the last part of the 3.12 release.

For the mac80211 bits, Johannes says:

"I have two DFS fixes (ath9k already supports DFS) and a fix for a
pointer race."

And...

"In this round for mac80211-next I have:
 * mesh channel switch support
 * a CCM rewrite, using potential hardware offloads
 * SMPS for AP mode
 * RF-kill GPIO driver updates to make it usable as an ACPI driver
 * regulatory improvements
 * documentation fixes
 * DFS for IBSS mode
 * and a few small other fixes/improvements"

For the TI driver bits, Luca says:

"Some patches intended for 3.13.  Eliad continues upstreaming pending
patches from the internal tree."

For the iwlwifi bits, Emmanuel says:

"There are a few fixes from Johannes mostly clean up patches. We have
also a few other fixes that are relevant for the new firmware that has
not been released yet."

For the Bluetooth bits, Gustavo says:

"A last fix to the 3.12. I ended forgetting to send it before, I hope we can
still make the way to 3.12. It is a revert and it fixes an issue with bluetooth
suspend/hibernate that had many bug reports. Please pull or let me know of any
problems. Thanks!"  (Obviously, that one didn't make 3.12...)

Also...

"One more big pull request for 3.13. These are the patches we queued during
last week. Here you will find a lot of improvements to the HCI and L2CAP and
MGMT layers with the main ones being a better debugfs support and end of work
of splitting L2CAP into Core and Socket parts."

Additionally, there is one ath9k patch to enable DFS in IBSS mode for
that driver.

I appreciate your consideration for taking this extra pull request
this cycle.  Please let me know if there are problems!

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next into for-davem

While testing virtio_net and skb_segment() changes, Hannes reported
that UFO was sending wrong frames.

It appears this was introduced by a recent commit :
8c3a897b ("inet: restore gso for vxlan")

The old condition to perform IP frag was :

tunnel = !!skb->encapsulation;
...
        if (!tunnel && proto == IPPROTO_UDP) {

So the new one should be :

udpfrag = !skb->encapsulation && proto == IPPROTO_UDP;
...
        if (udpfrag) {

Initialization of udpfrag must be done before call
to ops->callbacks.gso_segment(skb, features), as
skb_udp_tunnel_segment() clears skb->encapsulation

(We want udpfrag to be true for UFO, false for VXLAN)

Changing MTU size of an xgmac network interface while it is active can
cause a panic like

  skbuff: skb_over_panic: text:c03bc62c len:1090 put:1090 head:edfb6900 data:edfb6942 tail:0xedfb6d84 end:0xedfb6bc0 dev:eth0

  PC is at skb_panic+0x64/0x70
  LR is at wake_up_klogd+0x5c/0x68

This happens because xgmac_change_mtu modifies dev->mtu before the
network interface is quiesced. And thus there still might be buffers
in use which have a buffer size based on the old MTU.

To fix this I moved the change of dev->mtu after the call to
xgmac_stop.

Another modification is required (in xgmac_stop) to ensure that
xgmac_xmit is really not called anymore (xgmac_tx_complete might wake
up the queue again).

I've tested the fix by switching MTU size every second between 600 and
1500 while network traffic was going on. The test box survived a test
of several hours (until I've stopped it) whereas w/o this fix above
panic occurs after several minutes (at most).

Change since v1:
- remove call to netif_stop_queue at beginning of xgmac_stop
- use netif_tx_disable instead of locking+netif_stop_queue

l2 hardware accelerated macvlans

This patch adds support to offload macvlan net_devices to the
hardware. With these patches packets are pushed to the macvlan
net_device directly and do not pass through the lower dev.

The patches here have made it through multiple iterations
each with a slightly different focus. First I tried to
push these as a new link type called "VMDQ". The patches
shown here,

http://comments.gmane.org/gmane.linux.network/237617

Following this implementation I renamed the link type
"VSI" and addressed various comments. Finally Neil
Horman picked up the patches and integrated the offload
into the macvlan code. Here,

http://permalink.gmane.org/gmane.linux.network/285658

The attached series is clean-up of his patches, with a
few fixes.

If folks find this series acceptable there are a few
items we can work on next. First broadcast and multicast
will use the hardware even for local traffic with this
series. It would be best (I think) to use the software
path for macvlan to macvlan traffic and save the PCIe
bus. This depends on how much you value CPU time vs
PCIE bandwidth. This will need another patch series
to flush out.

Also this series only allows for layer 2 mac forwarding
where some hardware supports more interesting forwarding
capabilities. Integrating with OVS may be useful here.

As always any comments/feedback welcome.

My basic I/O test is here but I've also done some link
testing, SRIOV/DCB with macvlans and others,

Changelog:
v2: two fixes to ixgbe when all features DCB, FCoE, SR-IOV
    are enabled with macvlans. A VMDQ_P() reference
    should have been accel->pool and do not set the offset
    of the ring index from dfwd add call. The offset is used
    by SR-IOV so clearing it can cause SR-IOV quue index's
    to go sideways. With these fixes testing macvlan's with
    SRIOV enabled was successful.
v3: addressed Neil's comments in ixgbe

If appending a received fragment to the pending fragment chain
in a unicast link fails, the current code tries to force a retransmission
of the fragment by decrementing the 'next received sequence number'
field in the link. This is done under the assumption that the failure
is caused by an out-of-memory situation, an assumption that does
not hold true after the previous patch in this series.

A failure to append a fragment can now only be caused by a protocol
violation by the sending peer, and it must hence be assumed that it
is either malicious or buggy.  Either way, the correct behavior is now
to reset the link instead of trying to revert its sequence number.
So, this is what we do in this commit.

When the first fragment of a long data data message is received on a link, a
reassembly buffer large enough to hold the data from this and all subsequent
fragments of the message is allocated. The payload of each new fragment is
copied into this buffer upon arrival. When the last fragment is received, the
reassembled message is delivered upwards to the port/socket layer.

Not only is this an inefficient approach, but it may also cause bursts of
reassembly failures in low memory situations. since we may fail to allocate
the necessary large buffer in the first place. Furthermore, after 100 subsequent
such failures the link will be reset, something that in reality aggravates the
situation.

To remedy this problem, this patch introduces a different approach. Instead of
allocating a big reassembly buffer, we now append the arriving fragments
to a reassembly chain on the link, and deliver the whole chain up to the
socket layer once the last fragment has been received. This is safe because
the retransmission layer of a TIPC link always delivers packets in strict
uninterrupted order, to the reassembly layer as to all other upper layers.
Hence there can never be more than one fragment chain pending reassembly at
any given time in a link, and we can trust (but still verify) that the
fragments will be chained up in the correct order.

When a message fragment is received in a broadcast or unicast link,
the reception code will append the fragment payload to a big reassembly
buffer through a call to the function tipc_recv_fragm(). However, after
the return of that call, the logics goes on and passes the fragment
buffer to the function tipc_net_route_msg(), which will simply drop it.
This behavior is a remnant from the now obsolete multi-cluster
functionality, and has no relevance in the current code base.

Although currently harmless, this unnecessary call would be fatal
after applying the next patch in this series, which introduces
a completely new reassembly algorithm. So we change the code to
eliminate the redundant call.
