Most of it is typical driver and core updates, but there is the

I had a trivial workaround for gcc-5 or higher, but that didn't work
on gcc-4.9 unfortunately.
The only way I found to avoid the warnings for gcc-4.9, short of
initializing each of the arguments first was to change the calling
conventions to separate the error code from the umem pointer. This
avoids casting the error codes from one pointer to another incompatible
pointer, and lets gcc figure out when that the data is actually valid
whenever we return successfully.

When enabling many VFs, the total amount of DMA mappings increase
significantly. This causes DMA allocations to take a lot of time
since they are serialized in the kernel.
As a result the driver enters into fatal condition due to

MR cache for VFs.
PFs will still have a full cache and VFs cache can be manipulated

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.
That driver has a change_mtu method explicitly for sending
a message to the hardware. If that fails it returns an
error.
Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.
However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Pull rmda fixes from Doug Ledford.
"First round of -rc fixes.
Due to various issues, I've been away and couldn't send a pull request
for about three weeks. There were a number of -rc patches that built
up in the meantime (some where there already from the early -rc
stages). Obviously, there were way too many to send now, so I tried to
pare the list down to the more important patches for the -rc cycle.
Most of the code has had plenty of soak time at the various vendor's
testing setups, so I doubt there will be another -rc pull request this
cycle. I also tried to limit the patches to those with smaller
footprints, so even though a shortlog is longer than I would like, the
actual diffstat is mostly very small with the exception of just three
files that had more changes, and a couple files with pure removals.
Summary:
- Misc Intel hfi1 fixes
- Misc Mellanox mlx4, mlx5, and rxe fixes

The maximum page size in the mkey context is 2GB.
Until today, we didn't enforce this requirement in the code,
and therefore, if we got a page size larger than 2GB, we
have passed zeros in the log_page_shift instead of the actual value
and the registration failed.
This patch limits the driver to use compound pages of 2GB for mkeys.

Mellanox mlx5 core driver updates 2016-10-25
This series contains some updates and fixes of mlx5 core and
IB drivers with the addition of two features that demand
new low level commands and infrastructure updates.
- SRIOV VF max rate limit support
- mlx5e tc support for FWD rules with counter.
Needed for both net and rdma subsystems.
Updates and Fixes:
From Saeed Mahameed (2):
- mlx5 IB: Skip handling unknown mlx5 events
- Add ConnectX-5 PCIe 4.0 VF device ID
From Artemy Kovalyov (2):
- Update struct mlx5_ifc_xrqc_bits
- Ensure SRQ physical address structure endianness
From Eugenia Emantayev (1):
- Fix length of async_event_mask
New Features:
From Mohamad Haj Yahia (3): mlx5 SRIOV VF max rate limit support
- Introduce TSAR manipulation firmware commands
- Introduce E-switch QoS management
- Add SRIOV VF max rate configuration support
From Mark Bloch (7): mlx5e Tc support for FWD rule with counter
- Don't unlock fte while still using it
- Use fte status to decide on firmware command
- Refactor find_flow_rule
- Group similar rules under the same fte
- Add multi dest support
- Add option to add fwd rule with counter
- mlx5e tc support for FWD rule with counter
Mark here fixed two trivial issues with the flow steering core, and did
some refactoring in the flow steering API to support adding mulit destination
rules to the same hardware flow table entry at once. In the last two patches
added the ability to populate a flow rule with a flow counter to the same flow entry.
V2: Dropped some patches that added new structures without adding any usage of them.
Added SRIOV VF max rate configuration support patch that introduces
the usage of the TSAR infrastructure.
Added flow steering fixes and refactoring in addition to mlx5 tc
support for forward rule with counter.

Currently when calling mlx5_add_flow_rule we accept
only one flow destination, this commit allows to pass
multiple destinations.
This change forces us to change the return structure to a more
flexible one. We introduce a flow handle (struct mlx5_flow_handle),
it holds internally the number for rules created and holds an array
where each cell points the to a flow rule.
From the consumers (of mlx5_add_flow_rule) point of view this
change is only cosmetic and requires only to change the type
of the returned value they store.
From the core point of view, we now need to use a loop when
allocating and deleting rules (e.g given to us a flow handler).

This is done in two steps:
1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from
both ports arriving on PF0 root flowtable, so we will be able to catch
all raw-eth traffic on PF0.
2) Creation of LAG demux flowtable in order to direct all non-raw-eth
traffic back to its source port, assuring that normal Ethernet
traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

Since ib_query_port() in RoCE returns the state of its netdev as the port
state, it makes sense to propagate the port up/down events to ib_core
when the netdev port state changes, instead of relying on traditional

This also keeps both the event and ib_query_port() synchronized.

Now as all commands use mlx5 ifc interface, instead of doing two calls
for executing a command we embed command status checking into
mlx5_cmd_exec to simplify the interface.
Also we do here some cleanup for redundant software structures

Prior to this patch we assumed that modify QP commands have the
same layout.
In ConnectX-4 for each QP transition there is a specific command
and their layout can vary.
e.g: 2err/2rst commands don't have QP context in their layout and before
this patch we posted the QP context in those commands.
Fortunately the FW only checks the suffix of the commands and executes
them, while ignoring all invalid data sent after the valid command
layout.
This patch removes mlx5_modify_qp_mbox_in and changes
mlx5_core_qp_modify to receive the required transition and QP context
with opt_param_mask if needed. This way the caller is not required to
provide the command inbox layout and it will be generated automatically.
mlx5_core_qp_modify will generate the command inbox/outbox layouts
according to the requested transition and will fill the requested
parameters.

Number of outstanding_pi may overflow and as a result may indicate that
there are no elements in the queue. The effect of doing this is that the
MAD layer will get stuck waiting for completions. The MAD layer will
think that the QP is full - because it didn't receive these completions.
This fix changes it so the outstanding_pi number is increased
with 32-bit wraparound and is not limited to max_send_wr so
that the difference between outstanding_pi and outstanding_ci will
really indicate the number of outstanding completions.

Enable mlx5 based hardware to report TCP segmentation offload (TSO)
capabilities from kernel to user space. A TSO enabled NIC will accept
big chunks of data with sizes greater than MTU for TCP traffic. The TSO
engine will break the data into separate packets and will insert headers
automatically.
The capabilities are exposed to user space through query_device by uhw
directly. The following capabilities are reported:
1. The maximum payload size in bytes supported for segmentation by TSO
engine.
2. Bitmap showing which QP types are supported by TSO operation. The bitmap
is built by members from 'enmu ib_qp_type'. For example, similar code
should be performed if UD QP is supported:
supported_qpts |= 1 << IB_QPT_UD;

The driver exposes interfaces that directly relate to HW state.
Upon fatal error, consumers of these interfaces (ULPs) that rely
on completion of all their posted work-request could hang, thereby
introducing dependencies in shutdown order. To prevent this from
happening, we manage the relevant resources (CQs, QPs) that are used
by the device. Upon a fatal error, we now generate simulated
completions for outstanding WQEs that were not completed at the
time the HW was reset.
It includes invoking the completion event handler for all involved
CQs so that the ULPs will poll those CQs. When polled we return
simulated CQEs with IB_WC_WR_FLUSH_ERR return code enabling ULPs
to clean up their resources and not wait forever for completions
upon receiving remove_one.
The above change requires an extra check in the data path to make
sure that when device is in error state, the simulated CQEs will
be returned and no further WQEs will be posted.

By this patch, the user space library will be able to improve
performance using appropriate ringing DoorBell method according to the
memory type it asked for.
Currently only one mapping command is allowed for UARs:
MLX5_IB_MMAP_REGULAR_PAGE. Using this mapping, the kernel maps the
UARs to write-combining (WC) if the system supports it.
If the system is not supporting WC the UARs are mapped to
non-cached(NC). In this case the user space library can't tell which
mapping is applied.
This patch adds 2 new mapping commands: MLX5_IB_MMAP_WC_PAGE and
MLX5_IB_MMAP_NC_PAGE. For these commands the kernel maps exactly as
requested and fails if it can't.
Since there is no generic way to check if the requested memory region
can be mapped as WC, driver enables conclusive WC mapping only for
x86, PowerPC and ARM which support WC for the device's memory region.

The current mlx5 code disallows mapping the free running counter of
mlx5 based hardwares when PROT_EXEC is set.
Although this behaviour is correct, Linux does add an implicit VM_EXEC
to the vm_flags if the READ_IMPLIES_EXEC bit is set in the process
personality. This happens for example if the process stack is
executable.
This causes libmlx5 to output a warning and prevents the user from
reading the free running clock.
Executing the init segment of the hardware isn't a security risk
(at least no more than executing a process own stack), so we just
prevent writes to there.

The SRP initiator allows to set max_sectors to a value that exceeds
the largest amount of data that can be mapped at once with an mlx4
HCA using fast registration and a page size of 4 KB. Hence modify
ib_map_mr_sg() such that it can map partial sg-elements. If an
sg-element has been mapped partially, let the caller know
which fraction has been mapped by adjusting *sg_offset.

Currently, consumers of the flow steering infrastructure can't
choose their own flow table levels and are limited to one
flow table per level. This just waste levels.
Instead, we introduce here the possibility to use multiple
flow tables in a level. The user is free to connect these
flow tables, while following the rule (FTEs in FT of level x
could only point to FTs of level y where y > x).
In addition this patch switch the order of the create/destroy
flow tables of the NIC(vlan and main).

"Round two of 4.6 merge window patches.
This is a monster pull request. I held off on the hfi1 driver updates
(the hfi1 driver is intimately tied to the qib driver and the new
rdmavt software library that was created to help both of them) in my
first pull request. The hfi1/qib/rdmavt update is probably 90% of
this pull request. The hfi1 driver is being left in staging so that
it can be fixed up in regards to the API that Al and yourself didn't
like. Intel has agreed to do the work, but in the meantime, this
clears out 300+ patches in the backlog queue and brings my tree and
their tree closer to sync.
This also includes about 10 patches to the core and a few to mlx5 to
create an infrastructure for configuring SRIOV ports on IB devices.
That series includes one patch to the net core that we sent to netdev@
and Dave Miller with each of the three revisions to the series. We
didn't get any response to the patch, so we took that as implicit
approval.
Finally, this series includes Intel's new iWARP driver for their x722
cards. It's not nearly the beast as the hfi1 driver. It also has a
linux-next merge issue, but that has been resolved and it now passes
just fine.

Implement the IB defined callbacks used to manipulate the policy for the
link state, set GUIDs or get statistics information. This functionality
is added into a new file that will be used to add any SRIOV related
functionality to the mlx5 IB layer.
The following callbacks have been added:
mlx5_ib_get_vf_config
mlx5_ib_set_vf_link_state
mlx5_ib_get_vf_stats
mlx5_ib_set_vf_guid
In addition, publish whether this device is based on a virtual function.
In mlx5 supported devices, virtual functions are implemented as vHCAs.
vHCAs have their own QP number space so it is possible that two vHCAs
will use a QP with the same number at the same time.

API.
PFs may call mlx5_core_query_vport_counter with other_vport set to
indicate that they are querying a virtual function. The virtual
function to be queried is given by the vf parameter. Virtual function
numbering is zero based so the first VF is 0 and so on. When a PF
queries its own function, the other_vport parameter is cleared.
