Subject: [pull request][net-next V2 00/15] mlx5 Connection Tracking in NIC mode 

From: Saeed Mahameed <saeedm@...dia.com>

Hi Dave, Jakub,

This series adds the support for connection tracking in NIC mode,
and attached to this series some trivial cleanup patches.
v1->v2:
 - Remove "fixup!" comment from commit message (Jakub)
 - More information and use case description in the tag message
   (Cover-letter) (Jakub)

For more information please see tag log below.

Please pull and let me know if there is any problem.

Thanks,
Saeed.

  net/mlx5: remove unreachable return (2020-09-23 15:44:39 -0700)

mlx5-updates-2020-09-22

This series includes mlx5 updates

1) Add support for Connection Tracking offload in NIC mode.
   Supporting CT offload in NIC mode on Mellanox cards is useful for
   scenarios where the dual port NIC serves as a gateway between 2
   networks and forwards traffic between these networks.

   Since the traffic is not terminated on the host in this case,
   no use of SRIOV VFs and/or switchdev mode is required.

   Today Mellanox NIC cards already support offloading of packet forwarding
   between physical ports without going to the host so combining it with CT
   offloading allows users to create a gateway with forwarding and CT
   (Including NAT) offloading capabilities in non-switchdev mode.

   To support connection tracking in non-Switchdev mode (Single NIC mode),
   we need to make use of the current Connection tracking infrastructure
   implemented on top of E-Switch and the mlx5 generic flow table chains
   APIs, to make it work on non-Eswitch steering domain e.g. NIC RX domain,
   the following was performed:

 1.1) Refactor current flow steering chains infrastructure and
      updates TC nic mode implementation to use flow table chains.
 1.2) Refactor current Connection Tracking (CT) infrastructure to not
      assume E-switch backend, and make the CT layer agnostic to
      underlying steering mode (E-Switch/NIC)
 1.3) Plumbing to support CT offload in NIC mode.

2) Trivial code cleanups.
