Subject: [PATCH rdma-next v3 0/8] Driver part of the ECE

From: Leon Romanovsky <>

 * Squashed patch "RDMA/mlx5: Advertise ECE support" into
 "RDMA/mlx5: Set ECE options during modify QP".
 * Rebased on latest wip/jgg-rdma-next branch, commit a94dae867c56
 * Fixed wrong setting of pm_state field in mlx5 conversion patch
 * Removed DC support for now
 * Fixed compatibility issue of "old" kernel vs. "new" rdma-core. This
   is handled in extra patch.
 * Improved comments and commit messages after feedback from Yishai.
 * Added Mark Z. ROB tags



This is driver part of the RDMA-CM ECE series [1].
According to the IBTA, ECE data is completely vendor specific, so this
series extends mlx5_ib create_qp and modify_qp structs with extra field
to pass ECE options to/from the application.



Leon Romanovsky (8):
  net/mlx5: Add ability to read and write ECE options
  RDMA/mlx5: Get ECE options from FW during create QP
  RDMA/mlx5: Set ECE options during QP create
  RDMA/mlx5: Use direct modify QP implementation
  RDMA/mlx5: Remove manually crafted QP context the query call
  RDMA/mlx5: Convert modify QP to use MLX5_SET macros
  RDMA/mlx5: Set ECE options during modify QP
  RDMA/mlx5: Return ECE data after modify QP
