Assuming that the original code idea was to enable in-band sleeping
only if the setup_rome method returns succes and run in 'standard'
mode otherwise, we should not return setup_rome return value which
makes qca_setup fail if no rampatch/nvm file found.
This fixes BT issue on the dragonboard-820C p4 which includes the
following QCA controller:
hci0: Product:0x00000008
hci0: Patch :0x00000111
hci0: ROM :0x00000302
hci0: SOC :0x00000044
Since there is no rampatch for this controller revision, just make
it work as is.

tcp: better receiver autotuning

Back in linux-3.13 (commit b0983d3c9b13 ("tcp: fix dynamic right sizing"))
I addressed the pressing issues we had with receiver autotuning.
But DRS suffers from extra latencies caused by rcv_rtt_est.rtt_us
drifts. One common problem happens during slow start, since the
apparent RTT measured by the receiver can be inflated by ~50%,
at the end of one packet train.
Also, a single drop can delay read() calls by one RTT, meaning
tcp_rcv_space_adjust() can be called one RTT too late.
By replacing the tri-modal heuristic with a continuous function,
we can offset the effects of not growing 'at the optimal time'.
The curve of the function matches prior behavior if the space
increased by 25% and 50% exactly.
Cost of added multiply/divide is small, considering a TCP flow
typically would run this part of the code few times in its life.
I tested this patch with 100 ms RTT / 1% loss link, 100 runs
of (netperf -l 5), and got an average throughput of 4600 Mbit
instead of 1700 Mbit.

While rcvbuf is properly clamped by tcp_rmem[2], rcvwin
is left to a potentially too big value.
It has no serious effect, since :
1) tcp_grow_window() has very strict checks.
2) window_clamp can be mangled by user space to any value anyway.
tcp_init_buffer_space() and companions use tcp_full_space(),
we use tcp_win_from_space() to avoid reloading sk->sk_rcvbuf

nfp: dead code, clean ups and slight improvements
This series contains small clean ups from John and Carl, and brings
no functional changes.
John's improvements target the flower code. First he makes sure we don't
allocate space in FW request messages for MAC matches if the TC rule does
not contain any. The remaining two patches remove some dead code and
unused defines.
Carl follows up with a slight optimization to his recent ethtool FW state

dumped item.

Convert the requested dump level parameter to big-endian at the start of

compare and assign it directly where needed in the traversal and prolog

The GPIO polarity passed to phy-reset-gpio is ignored by the FEC
driver and it is assumed to be active low.
It can be active high only when the 'phy-reset-active-high' property

====================
sctp: Implement Stream Interleave: The I-DATA Chunk Supporting User Message Interleaving
Stream Interleave would be Implemented in two Parts:
1. The I-DATA Chunk Supporting User Message Interleaving
2. Interaction with Other SCTP Extensions
Overview in section 1.1 of RFC8260 for Part 1:
This document describes a new chunk carrying payload data called
I-DATA. This chunk incorporates the properties of the current SCTP
DATA chunk, all the flags and fields except the Stream Sequence
Number (SSN), and also adds two new fields in its chunk header -- the
Fragment Sequence Number (FSN) and the Message Identifier (MID). The
FSN is only used for reassembling all fragments that have the same
MID and the same ordering property. The TSN is only used for the
reliable transfer in combination with Selective Acknowledgment (SACK)
chunks.
In addition, the MID is also used for ensuring ordered delivery
instead of using the stream sequence number (the I-DATA chunk omits
an SSN).
As the 1st part of Stream Interleave Implementation, this patchset adds
an ops framework named sctp_stream_interleave with a bunch of stuff that
does lots of things needed somewhere.
Then it defines sctp_stream_interleave_0 to work for normal DATA chunks
and sctp_stream_interleave_1 for I-DATA chunks.
With these functions, hundreds of if-else checks for the different process
on I-DATA chunks would be avoided. Besides, very few codes could be shared
in these two function sets.
In this patchset, it adds some basic variables, structures and socket
options firstly, then implement these functions one by one to add the
procedures for ordered idata gradually, at last adjusts some codes to
make them work for unordered idata.
To make it safe to be implemented and also not break the normal data
chunk process, this feature can't be enabled to use until all stream
interleave codes are completely accomplished.
v1 -> v2:
- fixed a checkpatch warning that a blank line was missed.
- avoided a kbuild warning reported from gcc-4.9.

Unordered idata process is more complicated than unordered data:
- It has to add mid into sctp_stream_out to save the next mid value,
which is separated from ordered idata's.
- To support pd for unordered idata, another mid and pd_mode need to
be added to save the message id and pd state in sctp_stream_in.
- To make unordered idata reasm easier, it adds a new event queue
to save frags for idata.
The patch mostly adds the samilar reasm functions for unordered idata
as ordered idata's, and also adjusts some other codes on assign_mid,
abort_pd and ulpevent_data for idata.

abort_pd is added as a member of sctp_stream_interleave, used to abort
partial delivery for data or idata, called in sctp_cmd_assoc_failed.
Since stream interleave allows to do partial delivery for each stream
at the same time, sctp_intl_abort_pd for idata would be very different
from the old function sctp_ulpq_abort_pd for data.
Note that sctp_ulpevent_make_pdapi will support per stream in this
patch by adding pdapi_stream and pdapi_seq in sctp_pdapi_event, as
described in section 6.1.7 of RFC6458.

ulpevent_data is added as a member of sctp_stream_interleave, used to
do the most process in ulpq, including to convert data or idata chunk
to event, reasm them in reasm queue and put them in lobby queue in
right order, and deliver them up to user sk rx queue.
This procedure is described in section 2.2.3 of RFC8260.
It adds most functions for idata here to do the similar process as
the old functions for data. But since the details are very different
between them, the old functions can not be reused for idata.
event->ssn and event->ppid settings are moved to ulpevent_data from
sctp_ulpevent_make_rcvmsg, so that sctp_ulpevent_make_rcvmsg could
work for both data and idata.
Note that mid is added in sctp_ulpevent for idata, __packed has to
be used for defining sctp_ulpevent, or it would exceeds the skb cb
that saves a sctp_ulpevent variable for ulp layer process.

validate_data is added as a member of sctp_stream_interleave, used

If this check fails, an abort packet will be sent, as said in
section 2.2.3 of RFC8260.
It also adds the process for idata in rx path. As Marcelo pointed
out, there's no need to add event table for idata, but just share
chunk_event_table with data's. It would drop data chunk for idata
and drop idata chunk for data by calling validate_data in
sctp_eat_data.
As last patch did, it also replaces sizeof(struct sctp_data_chunk)
with sctp_datachk_len for rx path.
After this patch, the idata can be accepted and delivered to ulp

and sctp_chunk_assign_mid is added for sctp_stream_interleave_1.

All sizeof(struct sctp_data_chunk) in tx path is replaced with
sctp_datachk_len, to make it right for idata as well. And also
adjust sctp_chunk_is_data for SCTP_CID_I_DATA.
After this patch, idata can be built and sent in tx path.
Note that if sp strm_interleave is set, it has to wait_connect in

To avoid hundreds of checks for the different process on I-DATA chunk,
struct sctp_stream_interleave is defined as a group of functions used
to replace the codes in some place where it needs to do different job
according to if the asoc intl_enabled is set.
With these ops, it only needs to initialize asoc->stream.si with
sctp_stream_interleave_0 for normal data if asoc intl_enable is 0,
or sctp_stream_interleave_1 for idata if asoc intl_enable is set in
sctp_stream_init.
After that, the members in asoc->stream.si can be used directly in
some special places without checking asoc intl_enable.
make_datafrag is the first member for sctp_stream_interleave, it's
used to make data or idata frags, called in sctp_datamsg_from_user.
The old function sctp_make_datafrag_empty needs to be adjust some
to fit in this ops.
Note that as idata and data chunks have different length, it also
defines data_chunk_len for sctp_stream_interleave to describe the
chunk size.

netns intl_enable would be set via procfs, but that is not added yet
until all stream interleave codes are completely implemented; asoc
intl_enable will be set when doing 4-shakehands.
sp strm_interleave can be set by sockopt SCTP_INTERLEAVING_SUPPORTED
which is also added in this patch. This socket option is defined in
section 4.3.1 of RFC8260.
Note that strm_interleave can only be set by sockopt when both netns

Packets that don't have dest mac as the mac of the master device should
not be entertained by the IPvlan rx-handler. This is mostly true as the
packet path mostly takes care of that, except when the master device is
a virtual device. As demonstrated in the following case -
ip netns add ns1
ip link add ve1 type veth peer name ve2
ip link add link ve2 name iv1 type ipvlan mode l2
ip link set dev iv1 netns ns1
ip link set ve1 up
ip link set ve2 up
ip -n ns1 link set iv1 up
ip addr add 192.168.10.1/24 dev ve1
ip -n ns1 addr 192.168.10.2/24 dev iv1
ping -c2 192.168.10.2
<Works!>
ip neigh show dev ve1
ip neigh show 192.168.10.2 lladdr <random> dev ve1
ping -c2 192.168.10.2
<Still works! Wrong!!>

This function is like rhashtable_walk_next except that it only returns
the current element in the inter and does not advance the iter.
This patch also creates __rhashtable_walk_find_next. It finds the next
element in the table when the entry cached in iter is NULL or at the end
of a slot. __rhashtable_walk_find_next is called from
rhashtable_walk_next and rhastable_walk_peek.
end_of_table is an added field to the iter structure. This indicates
that the end of table was reached (walker.tbl being NULL is not a
sufficient condition for end of table).

Most callers of rhashtable_walk_start don't care about a resize event
which is indicated by a return value of -EAGAIN. So calls to
rhashtable_walk_start are wrapped wih code to ignore -EAGAIN. Something
like this is common:
ret = rhashtable_walk_start(rhiter);
if (ret && ret != -EAGAIN)
goto out;
Since zero and -EAGAIN are the only possible return values from the
function this check is pointless. The condition never evaluates to true.
This patch changes rhashtable_walk_start to return void. This simplifies
code for the callers that ignore -EAGAIN. For the few cases where the
caller cares about the resize event, particularly where the table can be
walked in mulitple parts for netlink or seq file dump, the function
rhashtable_walk_start_check has been added that returns -EAGAIN on a
resize event.

Pull media fixes from Mauro Carvalho Chehab:
"A series of fixes for the media subsytem:
- The largest amount of fixes in this series is with regards to
comments that aren't kernel-doc, but start with "/**".
A new check added for 4.15 makes it to produce a *huge* amount of
new warnings (I'm compiling here with W=1). Most of the patches in
this series fix those.
No code changes - just comment changes at the source files
- rc: some fixed in order to better handle RC repetition codes
- v4l-async: use the v4l2_dev from the root notifier when matching
sub-devices
- v4l2-fwnode: Check subdev count after checking port
- ov 13858 and et8ek8: compilation fix with randconfigs
- usbtv: a trivial new USB ID addition

Pull powerpc fixes from Michael Ellerman:
"One notable fix for kexec on Power9, where we were not clearing MMU
PID properly which sometimes leads to hangs. Finally debugged to a

A revert of a patch which tried to rework our panic handling to get
more output on the console, but inadvertently broke reporting the
panic to the hypervisor, which apparently people care about.
Then a fix for an oops in the PMU code, and finally some s/%p/%px/ in
xmon.

====================
pull-request: can 2017-12-08
this is a pull request of 6 patches for net/master.
Martin Kelly provides 5 patches for various USB based CAN drivers, that
properly cancel the URBs on adapter unplug, so that the driver doesn't
end up in an endless loop. Stephane Grosjean provides a patch to restart
the tx queue if zero length packages are transmitted.
