[PATCH for-next V2 00/15][PULL request] Mellanox mlx5 core driver updates 2016-10-25

[Saeed Mahameed]

Hi Dave and Doug,

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.

The following changes since commit a909d3e636995ba7c349e2ca5dbb528154d4ac30
    Linux 4.9-rc3

are available in the git repository at:
    git://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git tags/shared-for-4.10-1

[PATCH for-next V2 06/15] net/mlx5: Introduce TSAR manipulation firmware commands

[Saeed Mahameed]

From: Mohamad Haj Yahia <mohamad-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

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.

[PATCH for-next V2 07/15] net/mlx5: Introduce E-switch QoS management

[Saeed Mahameed]

From: Mohamad Haj Yahia <mohamad@mellanox.com>

Add TSAR to the eswitch which will act as the vports rate limiter.
Create/Destroy TSAR on Enable/Dsiable SRIOV.
Attach/Detach vport to eswitch TSAR on Enable/Disable vport.

[PATCH for-next V2 09/15] net/mlx5: Don't unlock fte while still using it

[Saeed Mahameed]

From: Mark Bloch <markb@mellanox.com>

When adding a new rule to an fte, we need to hold the fte lock
until we add that rule to the fte and increase the fte ref count.

[PATCH for-next V2 10/15] net/mlx5: Use fte status to decide on firmware command

[Saeed Mahameed]

From: Mark Bloch <markb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

An fte status becomes FS_FTE_STATUS_EXISTING only after it was
created in HW. We can use this in order to simplify the logic on
what firmware command to use. If the status isn't FS_FTE_STATUS_EXISTING
we need to create the fte, otherwise we need only to update it.

From: Mark Bloch <markb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

The way we compare between two dests will need to be used in other

[PATCH for-next V2 12/15] net/mlx5: Group similer rules under the same fte

[Saeed Mahameed]

From: Mark Bloch <markb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

When adding a new rule, if we can match it with compare_match_value and
flow tag we might be able to insert the rule to the same fte.
In order to do that, there must be an overlap between the actions of the
fte and the new rule.

When updating the action of an existing fte, we must tell the firmware
we are doing so.

[PATCH for-next V2 13/15] net/mlx5: Add multi dest support

[Saeed Mahameed]

From: Mark Bloch <markb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

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).

[PATCH for-next V2 14/15] net/mlx5: Add option to add fwd rule with counter

[Saeed Mahameed]

From: Mark Bloch <markb@mellanox.com>

Currently the code supports only drop rules to possess counters,
add that ability also for fwd rules.

[PATCH for-next V2 15/15] net/mlx5e: Add tc support for FWD rule with counter

[Saeed Mahameed]

From: Mark Bloch <markb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

When creating a FWD rule using tc create also a HW counter
for this rule.
