[pull request][for-next V3 00/11] Mellanox, mlx5 E-Switch updates 2017-12-19

From: Saeed Mahameed <hidden>
Date: 2017-12-28 23:23:03 

Hi Dave and Doug,

==============
This series includes updates for mlx5 E-Switch infrastructures,
to be merged into net-next and rdma-next trees.

Mark's patches provide E-Switch refactoring that generalize the mlx5
E-Switch vf representors interfaces and data structures. The serious is
mainly focused on moving ethernet (netdev) specific representors logic out
of E-Switch (eswitch.c) into mlx5e representor module (en_rep.c), which
provides better separation and allows future support for other types of vf
representors (e.g. RDMA).

Gal's patches at the end of this serious, provide a simple syntax fix and
two other patches that handles vport ingress/egress ACL steering name
spaces to be aligned with the Firmware/Hardware specs.
===============

V1->V2:
 - Addressed coding style comments in patches #1 and #7
 - The series is still based on rc4, as now I see net-next is also @rc4.

V2->V3:
 - Fixed compilation warning, reported by Dave.

Please pull and let me know if there's any problem.

Thanks,
Saeed.

[for-next V3 04/11] net/mlx5: E-Switch, Move mlx5e only logic outside E-Switch

From: Saeed Mahameed <hidden>
Date: 2017-12-28 23:27:17 

From: Mark Bloch <redacted>

In our pursuit to cleanup e-switch sub-module from mlx5e specific code,
we move the functions that insert/remove the flow steering rules that
allow mlx5e representors to send packets directly to VFs into the EN
driver code.

[for-next V3 06/11] net/mlx5e: Move ethernet representors data into separate struct

From: Saeed Mahameed <hidden>
Date: 2017-12-28 23:27:22 

From: Mark Bloch <redacted>

Ethernet representors have a need to store data which is applicable
only for them. Create a priv void pointer in struct mlx5_eswitch_rep
and move mlx5e to store the relevant data there. As part of this change
we also initialize rep_if in mlx5e_rep_register_vf_vports() as otherwise the
E-Switch code will copy a priv value which is garbage.

We also rename mlx5_eswitch_get_uplink_netdev() to
mlx5_eswitch_get_uplink_priv() and make it return void *.
This way E-Switch code doesn't need to deal with net devices and
we leave the task of getting it to mlx5e.

[for-next V3 05/11] net/mlx5: E-Switch, Create a dedicated send to vport rule deletion function

From: Saeed Mahameed <hidden>
Date: 2017-12-28 23:27:22 

From: Mark Bloch <redacted>

In order for representors to send packets directly to VFs we use an
E-Switch function which insert special rules into the HW. For symmetry
create an E-Switch function that deletes these rules as well.

[for-next V3 11/11] net/mlx5: Separate ingress/egress namespaces for each vport

From: Saeed Mahameed <hidden>
Date: 2017-12-28 23:27:23 

From: Gal Pressman <redacted>

Each vport has its own root flow table for the ACL flow tables and root
flow table is per namespace, therefore we should create a namespace for
each vport.

Fixes: efdc810ba39d ("net/mlx5: Flow steering, Add vport ACL support")

[for-next V3 07/11] net/mlx5: E-Switch, Create generic header struct to be used by representors

From: Saeed Mahameed <hidden>
Date: 2017-12-28 23:27:23 

From: Mark Bloch <redacted>

Now that we don't store type dependent data in struct mlx5_eswitch_rep
we can create a generic interface, and representor type.

struct mlx5_eswitch_rep will store an array of interfaces, each
interface is used by a different representor type.

Once we moved to a more generic interface, rdma driver representors can
be added and utilize the same mechanism as the Ethernet driver
representors use.

[for-next V3 09/11] net/mlx5e: E-Switch, Use the name of static array instead of its address

From: Saeed Mahameed <hidden>
Date: 2017-12-28 23:27:23 

From: Gal Pressman <redacted>

Using the address of a static array is the same as using its name (in
this specific use-case), but it's confusing and makes the code less
readable.

Fixes: 1bd27b11c1df ("net/mlx5: Introduce E-switch QoS management")
Fixes: bd77bf1cb595 ("net/mlx5: Add SRIOV VF max rate configuration support")

Re: [pull request][for-next V3 00/11] Mellanox, mlx5 E-Switch updates 2017-12-19

From: David Miller <davem@davemloft.net>
Date: 2017-12-29 00:46:27 

From: Saeed Mahameed <redacted>

==============
This series includes updates for mlx5 E-Switch infrastructures,
to be merged into net-next and rdma-next trees.

Mark's patches provide E-Switch refactoring that generalize the mlx5
E-Switch vf representors interfaces and data structures. The serious is
mainly focused on moving ethernet (netdev) specific representors logic out
of E-Switch (eswitch.c) into mlx5e representor module (en_rep.c), which
provides better separation and allows future support for other types of vf
representors (e.g. RDMA).

Gal's patches at the end of this serious, provide a simple syntax fix and
two other patches that handles vport ingress/egress ACL steering name
spaces to be aligned with the Firmware/Hardware specs.
===============

V1->V2:
 - Addressed coding style comments in patches #1 and #7
 - The series is still based on rc4, as now I see net-next is also @rc4.

V2->V3:
 - Fixed compilation warning, reported by Dave.

Please pull and let me know if there's any problem.
Looks good, pulled, thank you.
