This patch add support for X552 XFI backplane interface. The XFI
backplane requires a custom tuned link. HW/FW owns the link config
for XF backplane and SW must not interfere with it.

As pr_cont output can be interleaved by other processes,
using pr_cont should be avoided where possible.
Miscellanea:
- Use a temporary pointer to hold the next descriptions and
consolidate the pr_cont uses
- Use the temporary buffer to hold the 8 u32 register values and
emit those in a single go
- Coalesce formats and logging neatening around those changes
- Fix a defective output for the rx ring entry description when
also emitting rx_buffer_info data
This reduces overall object size a tiny bit too.

We disable VxLAN offload when more than 1 UDP port is added to the driver,
since Skyhawk doesn't support offload with multiple ports. The existing
driver design expects the user to delete all port configurations and create
a configuration with a single UDP port for VxLAN offload to be re-enabled.
Remove this restriction by tracking the ports added and re-enabling offload
when ports get deleted and only 1 port is left.

This patch adds extended statistics reporting to ethtool.
In summary, this patch,
- adds ethtool.h with the statistics register definitions

====================
ftgmac100: Rework batch 5 - Features
This is the third spin of the fifth and last batch of
updates to the ftgmac100 driver.
This contains a few additional "features" such as:
- Support for ethtool n-way reset
- Multicast filtering & promisc support
- Vlan offload
- netpoll
And a couple of misc bits. This also adds the device-tree binding
documentation.
v2. - Addresses review comments and adds a new patch fixing a
theorical ordering issue in my new NAPI poll implementation
- Add a bug fix (Patch 8/9) for a potential ordering issue
in the new NAPI poll code.
v3. - Rebase on net-next (fix conflict with an unrelated #include
change series)
- Update DT bindings better describing accepted phy-mode values

We need to ensure the loads from the descriptor are done after the
MMIO store clearing the interrupts has completed, otherwise we
might still miss work.
A read back from the MMIO register will "push" the posted store and
ioread32 has a barrier on weakly aordered architectures that will
order subsequent accesses.

sctp: add proper process for duplicated stream reconf requests
Now sctp stream reconf will process a request again even if it's seqno
is less than asoc->strreset_inseq. It may cause a replay attack.

This patch is to fix the replay attack issue for strreset asoc requests.
When a duplicated strreset asoc request is received, reply it with bad
seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the
result saved in asoc if it's seqno >= asoc->strreset_inseq - 2.
But note that if the result saved in asoc is performed, the sender's next
tsn and receiver's next tsn for the response chunk should be set. It's
safe to get them from asoc. Because if it's changed, which means the peer
has received the response already, the new response with wrong tsn won't
be accepted by peer.

This patch is to fix the replay attack issue for strreset and addstrm in
requests.
When a duplicated strreset in or addstrm in request is received, reply it
with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with
the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2.
For strreset in or addstrm in request, if the receiver side processes it
successfully, a strreset out or addstrm out request(as a response for that
request) will be sent back to peer. reconf_time will retransmit the out
request even if it's lost.
So when receiving a duplicated strreset in or addstrm in request and it's
result was performed, it shouldn't reply this request, but drop it instead.

Now sctp stream reconf will process a request again even if it's seqno is
less than asoc->strreset_inseq.
If one request has been done successfully and some data chunks have been
accepted and then a duplicated strreset out request comes, the streamin's
ssn will be cleared. It will cause that stream will never receive chunks
any more because of unsynchronized ssn. It allows a replay attack.
A similar issue also exists when processing addstrm out requests. It will
cause more extra streams being added.
This patch is to fix it by saving the last 2 results into asoc. When a
duplicated strreset out or addstrm out request is received, reply it with
bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the
result saved in asoc if it's seqno >= asoc->strreset_inseq - 2.
Note that it saves last 2 results instead of only last 1 result, because
two requests can be sent together in one chunk.
And note that when receiving a duplicated request, the receiver side will
still reply it even if the peer has received the response. It's safe, As
the response will be dropped by the peer.

Pull ftrace testcase update from Steven Rostedt:
"While testing my development branch, without the fix for the pid use
after free bug, the selftest that Namhyung added triggers it. I
figured it would be good to add the test for the bug after the fix,
such that it does not exist without the fix.
I added another patch that lets the test only test part of the pid
filtering, and ignores the function-fork (filtering on children as
well) if the function-fork feature does not exist. This feature is
added by Namhyung just before he added this test. But since the test
tests both with and without the feature, it would be good to let it
not fail if the feature does not exist"
