Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull Mellanox rdma updates from Doug Ledford: "Mellanox specific updates for 4.11 merge window Because the Mellanox code required being based on a net-next tree, I keept it separate from the remainder of the RDMA stack submission that is based on 4.10-rc3. This branch contains: - Various mlx4 and mlx5 fixes and minor changes - Support for adding a tag match rule to flow specs - Support for cvlan offload operation for raw ethernet QPs - A change to the core IB code to recognize raw eth capabilities and enumerate them (touches non-Mellanox code) - Implicit On-Demand Paging memory registration support" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (40 commits) IB/mlx5: Fix configuration of port capabilities IB/mlx4: Take source GID by index from HW GID table IB/mlx5: Fix blue flame buffer size calculation IB/mlx4: Remove unused variable from function declaration IB: Query ports via the core instead of direct into the driver IB: Add protocol for USNIC IB/mlx4: Support raw packet protocol IB/mlx5: Support raw packet protocol IB/core: Add raw packet protocol IB/mlx5: Add implicit MR support IB/mlx5: Expose MR cache for mlx5_ib IB/mlx5: Add null_mkey access IB/umem: Indicate that process is being terminated IB/umem: Update on demand page (ODP) support IB/core: Add implicit MR flag IB/mlx5: Support creation of a WQ with scatter FCS offload IB/mlx5: Enable QP creation with cvlan offload IB/mlx5: Enable WQ creation and modification with cvlan offload IB/mlx5: Expose vlan offloads capabilities IB/uverbs: Enable QP creation with cvlan offload ...
