This is illegal to use atomic_set(&page->_count, 2) even if we 'own'
the page. Other entities in the kernel need to use get_page_unless_zero()
to get a reference to the page before testing page properties, so we could
loose a refcount increment.

The KSZ8021 and KSZ8031 support RMII reference input clocks of 25MHz
and 50MHz. Both PHYs differ in the default frequency they expect
after reset. If this differs from the actual input clock, then
register 0x1f bit 7 must be changed.

This patch addresses a kernel unaligned access bug seen on a sparc64 system
with an igb adapter. Specifically the __skb_flow_get_ports was returning a
be32 pointer which was then having the value directly returned.
In order to prevent this it is actually easier to simply not populate the
ports or address values when an skb is not present. In this case the
assumption is that the data isn't needed and rather than slow down the
faster aligned accesses by making them have to assume the unaligned path on
architectures that don't support efficent unaligned access it makes more
sense to simply switch off the bits that were copying the source and
destination address/port for the case where we only care about the protocol
types and lengths which are normally 16 bit fields anyway.

====================
macvlan: optimize receive path
So after porting this optimization to net-next, I found that the netperf
results of TCP_RR regress right at the maximum peak of transactions/sec. That
is as I increase the number of threads via the first argument to super_netperf,
the number of transactions/sec keep increasing, peak, and then start
decreasing. It is right at the peak, that I see a small regression with this
patch (see results in patch 2/2).
Without the patch, the ksoftirqd threads are the top cpu consumers threads on
the system, since the extra 'netif_rx()', is queuing more softirq work, whereas
with the patch, the ksoftirqd threads are below all of the 'netserver' threads
in terms of their cpu usage. So there appears to be some interaction between how
softirqs are serviced at the peak here and this patch. I think the test results
are still supportive of this approach, but I wanted to be clear on my findings.

The netif_rx() call on the fast path of macvlan_handle_frame() appears to
be there to ensure that we properly throttle incoming packets. However, it
would appear as though the proper throttling is already in place for all
possible ingress paths, and that the call is redundant. If packets are arriving
from the physical NIC, we've already throttled them by this point. Otherwise,
if they are coming via macvlan_queue_xmit(), it calls either
'dev_forward_skb()', which ends up calling netif_rx_internal(), or else in
the broadcast case, we are throttling via macvlan_broadcast_enqueue().
The test results below are from off the box to an lxc instance running macvlan.
Once the tranactions/sec stop increasing, the cpu idle time has gone to 0.
Results are from a quad core Intel E3-1270 V2@3.50GHz box with bnx2x 10G card.

Restore the quota fairness between qdisc's, that we broke with commit
5772e9a346 ("qdisc: bulk dequeue support for qdiscs with TCQ_F_ONETXQUEUE").
Before that commit, the quota in __qdisc_run() were in packets as
dequeue_skb() would only dequeue a single packet, that assumption
broke with bulk dequeue.
We choose not to account for the number of packets inside the TSO/GSO
packets (accessable via "skb_gso_segs"). As the previous fairness
also had this "defect". Thus, GSO/TSO packets counts as a single
packet.
Further more, we choose to slack on accuracy, by allowing a bulk
dequeue try_bulk_dequeue_skb() to exceed the "packets" limit, only
limited by the BQL bytelimit. This is done because BQL prefers to get
its full budget for appropriate feedback from TX completion.
In future, we might consider reworking this further and, if it allows,
switch to a time-based model, as suggested by Eric. Right now, we only
restore old semantics.
Joint work with Eric, Hannes, Daniel and Jesper. Hannes wrote the
first patch in cooperation with Daniel and Jesper. Eric rewrote the
patch.

gianfar: ARM port driver updates (1/2)
This is the first round of driver portability fixes and clean-up
with the main purpose to make gianfar portable on ARM, for the ARM
based SoC that integrates the eTSEC ethernet controller - "ls1021a".
The patches primarily address compile time errors, when compiling
gianfar on ARM. They replace PPC specific functions and macros
with architecture independent ones, solve arch specific header
inclusions, guard code that relates to PPC only, and even address
some simple endianess issues (see MAC address setup patch).
The patches addressing the bulk of remaining endianess issues,
like handling DMA fields (BD and FCB), will follow with the second
round.

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

6) Support checksumming more smoothly and efficiently for

7) Add Broadcom SF2 switch driver to DSA layer, from Florian

8) eBPF now can load programs via a system call and has an extensive

9) Major overhaul of the packet scheduler to use RCU in several major
areas such as the classifiers and rate estimators. From John

through the arm-soc tree, like we have been doing for arm32.
This time, there is only one set of changes, adding support for the
Cavium "Thunder" Soc family. Since the changes are relatively small,
this includes Kconfig, defconfig and DT changes.
If all goes well, we will never require adding actual C source code
for platform support in arm64, given that the architecture is more
clearly defined and we have moved out a lot of the platform specifics
into device drivers for arm32 already"

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

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"
