Subject: [PATCH rdma-next 00/12] Add SRQ and XRC support for ODP MRs

From: Leon Romanovsky <leonro@...lanox.com>

Hi,

This series extend ODP to work with SRQ and XRC. Being both per-operation
(e.g. RDMA write, RDMA read and atomic) and per-transport (e.g. RC, UD and XRC),
we extend IB/core and mlx5 driver to provide needed information to user space.

Thanks

Moni Shoua (12):
  IB/mlx5: Fix locking SRQ object in ODP event
  IB/core: Allocate bit for SRQ ODP support
  IB/uverbs: Expose XRC ODP device capabilities
  IB/mlx5: Remove useless check in ODP handler
  IB/mlx5: Clean mlx5_ib_mr_responder_pfault_handler() signature
  IB/mlx5: Add XRC initiator ODP support
  IB/mlx5: Let read user wqe also from SRQ buffer
  IB/mlx5: Add ODP SRQ support
  IB/mlx5: Advertise SRQ ODP support for supported transports
  net/mlx5: Add XRC transport to ODP device capabilities layout
  IB/mlx5: Advertise XRC ODP support
  net/mlx5: Set ODP SRQ support in firmware
