Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma updates from Doug Ledford:
 "This is the complete update for the rdma stack for this release cycle.

  Most of it is typical driver and core updates, but there is the
  entirely new VMWare pvrdma driver. You may have noticed that there
  were changes in DaveM's pull request to the bnxt Ethernet driver to
  support a RoCE RDMA driver. The bnxt_re driver was tentatively set to
  be pulled in this release cycle, but it simply wasn't ready in time
  and was dropped (a few review comments still to address, and some
  multi-arch build issues like prefetch() not working across all
  arches).

  Summary:

   - shared mlx5 updates with net stack (will drop out on merge if
     Dave's tree has already been merged)

   - driver updates: cxgb4, hfi1, hns-roce, i40iw, mlx4, mlx5, qedr, rxe

   - debug cleanups

   - new connection rejection helpers

   - SRP updates

   - various misc fixes

   - new paravirt driver from vmware"

====================
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.

Mark Bloch 74491de937 net/mlx5: Add multi dest support
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).

Mohamad Haj Yahia 813f854053 net/mlx5: Introduce TSAR manipulation firmware commands
TSAR (stands for Transmit Scheduling ARbiter) is a hardware component
that is responsible for selecting the next entity to serve on the
transmit path.
The arbitration defines the QoS policy between the agents connected to
the TSAR.
The TSAR is a consist two main features:
1) BW Allocation between agents:
The TSAR implements a defecit weighted round robin between the agents.
Each agent attached to the TSAR is assigned with a weight and it is
awarded transmission tokens according to this weight.
2) Rate limer per agent:
Each agent attached to the TSAR is (optionally) assigned with a rate
limit.
TSAR will not allow scheduling for an agent exceeding its defined rate
limit.

In this patch we implement the API of manipulating the TSAR.

Mohamad Haj Yahia 04c0c1ab38 net/mlx5: PCI error recovery health care simulation
In case that the kernel PCI error handlers are not called, we will
trigger our own recovery flow.

The health work will give priority to the kernel pci error handlers to
recover the PCI by waiting for a small period, if the pci error handlers
are not triggered the manual recovery flow will be executed.

We don't save pci state in case of manual recovery because it will ruin the
pci configuration space and we will lose dma sync.

Currently there is a race between the health care work and the kernel
pci error handlers because both of them detect the error, the first one
to be called will do the error handling.
There is a chance that health care will disable the pci after resuming
pci slot.
Also create a separate WQ because now we will have two types of health
works, one for the error detection and one for the recovery.

Tom Herbert b8a4ddb2e8 net/mlx5: Add MLX5_ARRAY_SET64 to fix BUILD_BUG_ON
I am hitting this in mlx5:

drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c: In function
reclaim_pages_cmd.clone.0:
drivers/net/ethernet/mellanox/mlx5/core/pagealloc.c:346: error: call
to __compiletime_assert_346 declared with attribute error:
BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_out, pas[i]) % 64

to __compiletime_assert_291 declared with attribute error:
BUILD_BUG_ON failed: __mlx5_bit_off(manage_pages_in, pas[i]) % 64

Problem is that this is doing a BUILD_BUG_ON on a non-constant
expression because of trying to take offset of pas[i] in the
structure.

Fix is to create MLX5_ARRAY_SET64 that takes an additional argument
that is the field index to separate between BUILD_BUG_ON on the array
constant field and the indexed field to assign the value to.
There are two callers of MLX5_SET64 that are trying to get a variable
offset, change those to call MLX5_ARRAY_SET64 passing 'pas' and 'i'
as the arguments to use in the offset check and the indexed value
assignment.

Aviv Heller 3e75d4ebaa net/mlx5: Add LAG flow steering namespace
This namespace is used for LAG demux flowtable.

The idea is to position the LAG demux ft between
bypass and kernel flowtables, allowing raw-eth
traffic from both ports to be received by the PF0
IB device.

Aviv Heller aaff1bea16 net/mlx5: LAG demux flow table support
Add interfaces to allow the creation and destruction of a
LAG demux flow table.

It is a special flow table used during LAG for redirecting
non user-mode packets from PF0 to PF1 root ft, if a packet was
received on phys port two.

Returns PF0's netdev if mode is not active-backup,
or the PF netdev of the active slave when mode is
active-backup.

Aviv Heller 7907f23adc net/mlx5: Implement RoCE LAG feature
Available on dual port cards only, this feature keeps
track, using netdev LAG events, of the bonding
and link status of each port's PF netdev.

When both of the card's PF netdevs are enslaved to the
same bond/team master, and only them, LAG state
is active.

During LAG, only one IB device is present for both ports.

In addition to the above, this commit includes FW commands
used for managing the LAG, new facilities for adding and removing
a single device by interface, and port remap functionality according to
bond events.

Please note that this feature is currently used only for mimicking
Ethernet bonding for RoCE - netdevs functionality is not altered,
and their bonding continues to be managed solely by bond/team driver.

Aviv Heller 84df61ebc6 net/mlx5: Add HW interfaces used by LAG
Exposed LAG commands enum and layouts:
- CREATE_LAG
  HW enters LAG mode:
  RoCE traffic from port two is received on PF0 core dev.
  Allows to set tx_affinity (tx port) for QPs and TISes.
  Allows to port remap QPs and TISes, overriding their
  tx_affinity behavior.

- MODIFY_LAG
  Remap QPs and TISes to another port.

- QUERY_LAG
  Query whether LAG mode is active.

- DESTROY_LAG
  HW exits LAG mode, returning to non-LAG behavior.

- CREATE_VPORT_LAG
  Merge Ethernet flow steering, such that traffic received on port
  two jumps to PF0 root flow table.

  Available only in LAG mode.

- DESTROY_VPORT_LAG
  Ethernet flow steering returns to non-LAG behavior.

Caps added:
- lag_master
  Driver is in charge of managing the LAG.
  This is currently the only option.

- num_lag_ports
  LAG is supported only if this field's value is 2.

Other fields:
- QP/TIS tx port affinity
  During LAG, this field controls on which port a QP or TIS resides.

- TIS strict tx affinity
  When this field is set, the TIS will not be subject to port remap by
  CREATE_LAG/MODIFY_LAG.

- LAG demux flow table
  Flow table used for redirecting non user-space traffic back to
  PF1 root flow table, if the packet was received on port two.

Saeed Mahameed 1a412fb1ca {net,IB}/mlx5: Modify QP commands via mlx5 ifc
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.
