Scan condition iterator assumes that an interface is associated if
phy_ctxt is assigned, but this isn't the sutuation in P2P device.
OTOH P2P device is never associated so we can simply ignore it.

iwlwifi features a debug mechanism that allows to dump
binary data which is helpful to debug the firmware.
Until now, this data was made available for the userspace
through debugfs. For this exact purpose, devcoredump was
created. Move to the new infrastructure.

We used to need to include some headers in order to read the registers
and do all the calculations by ourselves, but this is not done anymore
(i.e. we let the firmware do this for us), so we don't need to include
those headers anymore.

For WMM-AC we may have to be changing QoS parameters while the
queues are being flushed. This is not relevant in the "drop"
case, but matters when we wait for the device to finish the
transmissions.
To allow this, do the actual waiting without holding the mutex.

Instead of checking if we are associated when suspending with wowlan

Take the WoWLAN handling code out of the main suspend function,
dividing it into three parts: get_config (which is used before the
firmware is switched), switch_to_d3 (which handles the rebooting of
the hardware with the D3 firmware) and config (which configures the D3
firmware for WoWLAN operation). This is necessary to prepare for the
net-detect implementation, which will use only the switch_to_d3 part
of this flow.

When mac80211 wants to ensure that a frame is sent, it calls
the flush() callback. Until now, iwldvm implemented this by
waiting that all the frames are sent (ACKed or timeout).
In case of weak signal, this can take a significant amount
of time, delaying the next connection (in case of roaming).
Many users have reported that the flush would take too long
leading to the following error messages to be printed:
iwlwifi 0000:03:00.0: fail to flush all tx fifo queues Q 2
iwlwifi 0000:03:00.0: Current SW read_ptr 161 write_ptr 201
iwl data: 00000000: 00 00 00 00 00 00 00 00 fe ff 01 00 00 00 00 00
[snip]
iwlwifi 0000:03:00.0: FH TRBs(0) = 0x00000000
[snip]
iwlwifi 0000:03:00.0: Q 0 is active and mapped to fifo 3 ra_tid 0x0000 [9,9]
[snip]
Instead of waiting for these packets, simply drop them. This
significantly improves the responsiveness of the network.
Note that all the queues are flushed, but the VO one. This
is not typically used by the applications and it likely
contains management frames that are useful for connection
or roaming.
This bug is tracked here:
https://bugzilla.kernel.org/show_bug.cgi?id=56581
But it is duplicated in distributions' trackers.
A simple search in Ubuntu's database led to these bugs:

Don't add the time event to the list. We added it several
times the same time event, which leads to an infinite loop
when walking the list.
Since we (currently) don't support more than one ROC for STA
vif at a time, enforce this and don't add the time event
to any list.
We were also missing the locking of the mutex which led to
a lockdep splat - fix that.

Pull networking updates from David Miller:
"Most notable changes in here:
1) By far the biggest accomplishment, thanks to a large range of
contributors, is the addition of multi-send for transmit. This is
the result of discussions back in Chicago, and the hard work of
several individuals.
Now, when the ->ndo_start_xmit() method of a driver sees
skb->xmit_more as true, it can choose to defer the doorbell
telling the driver to start processing the new TX queue entires.
skb->xmit_more means that the generic networking is guaranteed to
call the driver immediately with another SKB to send.
There is logic added to the qdisc layer to dequeue multiple
packets at a time, and the handling mis-predicted offloads in
software is now done with no locks held.
Finally, pktgen is extended to have a "burst" parameter that can
be used to test a multi-send implementation.
Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
virtio_net
Adding support is almost trivial, so export more drivers to
support this optimization soon.
I want to thank, in no particular or implied order, Jesper
Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
David Tat, Hannes Frederic Sowa, and Rusty Russell.
2) PTP and timestamping support in bnx2x, from Michal Kalderon.
3) Allow adjusting the rx_copybreak threshold for a driver via
ethtool, and add rx_copybreak support to enic driver. From
Govindarajulu Varadarajan.
4) Significant enhancements to the generic PHY layer and the bcm7xxx
driver in particular (EEE support, auto power down, etc.) from
Florian Fainelli.
5) Allow raw buffers to be used for flow dissection, allowing drivers
to determine the optimal "linear pull" size for devices that DMA
into pools of pages. The objective is to get exactly the
necessary amount of headers into the linear SKB area pre-pulled,
but no more. The new interface drivers use is eth_get_headlen().
From WANG Cong, with driver conversions (several had their own
by-hand duplicated implementations) by Alexander Duyck and Eric
Dumazet.
6) Support checksumming more smoothly and efficiently for
encapsulations, and add "foo over UDP" facility. From Tom
Herbert.
7) Add Broadcom SF2 switch driver to DSA layer, from Florian
Fainelli.
8) eBPF now can load programs via a system call and has an extensive
testsuite. Alexei Starovoitov and Daniel Borkmann.
9) Major overhaul of the packet scheduler to use RCU in several major
areas such as the classifiers and rate estimators. From John
Fastabend.
10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
Duyck.
11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
Dumazet.
12) Add Datacenter TCP congestion control algorithm support, From
Florian Westphal.
13) Reorganize sk_buff so that __copy_skb_header() is significantly
faster. From Eric Dumazet"

Pull ARM SoC driver updates from Arnd Bergmann:
"These are changes for drivers that are intimately tied to some SoC and
for some reason could not get merged through the respective subsystem
maintainer tree.
Most of the new code is for the Keystone Navigator driver, which is
new base support that is going to be needed for their hardware
accelerated network driver and other units.
Most of the commits are for moving old code around from at91 and omap
for things that are done in device drivers nowadays.
- at91: move reset, poweroff, memory and clocksource code into
drivers directories
- socfpga: add edac driver (through arm-soc, as requested by Boris)
- omap: move omap-intc code to drivers/irqchip
- sunxi: added an RTC driver for sun6i
- omap: mailbox driver related changes
- keystone: support for the "Navigator" component

Pull ARM SoC cleanups from Arnd Bergmann:
"This time around, the cleanup branch contains mostly code removal. A
number of board files for at91, imx and msm have become obsolete
because of the DT conversion and are now ready to be removed. The
OMAP platform has traditionally had its own DMA engine abstraction and
as this is being phased out, a lot of the original code is now unused
and can be removed as well.
S3C24xx can be simplified now that the restart code is a proper device
driver.
Finally, a number of cleanups in shmobile are done to prepare for the
addition of new code in other branches"

The tx_desc struct holds 8 __be64 values. The original code in
ring_tx_db() took a tx_desc pointer then casted it to an int pointer and
then casted it to a u64 pointer. It was confusing and triggered some
static checker warnings.
I have changed the cxgb_pio_copy() function to only take tx_desc
pointers. This isn't really a loss of flexibility because anything else
was buggy to begin with.
I also removed the casting on the destination pointer since that was
unnecessary and a bit messy.

Christophe Leroy says:
====================
net: fs_enet: Remove non NAPI RX and add NAPI for TX
When using a MPC8xx as a router, 'perf' shows a significant time spent in
fs_enet_interrupt() and fs_enet_start_xmit().
'perf annotate' shows that the time spent in fs_enet_start_xmit is indeed spent
between spin_unlock_irqrestore() and the following instruction, hence in
interrupt handling. This is due to the TX complete interrupt that fires after
each transmitted packet.
This patchset first remove all non NAPI handling as NAPI has become the only
mode for RX, then adds NAPI for handling TX complete.
This improves NAT TCP throughput by 21% on MPC885 with FEC.
Tested on MPC885 with FEC.
