IB/mlx5: Introduce async DEVX obj query API

2019-01-29T20:33:00Z

Introduce async DEVX obj query API to get the command response back to user space once it's ready without blocking when calling the firmware. The event's data includes a header with some meta data then the firmware output command data. The header includes: - The input 'wr_id' to let application recognizing the response. The input FD attribute is used to have the event data ready on. Downstream patches from this series will implement the file ops to let application read it.

RDMA/mlx5: Extend packet reformat verbs

2018-09-05T21:23:59Z

We expose new actions: L2_TO_L2_TUNNEL - A generic encap from L2 to L2, the data passed should be the encapsulating headers. L3_TUNNEL_TO_L2 - Will do decap where the inner packet starts from L3, the data should be mac or mac + vlan (14 or 18 bytes). L2_TO_L3_TUNNEL - Will do encap where is L2 of the original packet will not be included, the data should be the encapsulating header.

RDMA/mlx5: Add new flow action verb - packet reformat

2018-09-05T21:23:59Z

For now, only add L2_TUNNEL_TO_L2 option. This will allow to perform generic decap operation if the encapsulating protocol is L2 based, and the inner packet is also L2 based. For example this can be used to decap VXLAN packets. Signed-off-by: Mark Bloch Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/mlx5: Add a new flow action verb - modify header

2018-09-05T21:23:58Z

Expose the ability to create a flow action which changes packet headers. The data passed from userspace should be modify header actions as defined by HW specification. Signed-off-by: Mark Bloch Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

IB/mlx5: Add implementation for create and destroy action_xfrm

2018-04-04T18:06:26Z

Adding implementation in mlx5 driver to create and destroy action_xfrm object. This merely call the accel layer. A user may pass MLX5_IB_XFRM_FLAGS_REQUIRE_METADATA flag which states that [s]he expects a metadata header to be added to the payload. This header represents information regarding the transformation's state.
