2020-05-06RDMA: Allow ib_client's to fail when add() is calledJason Gunthorpe12-109/+124
When a client is added it isn't allowed to fail, but all the client's have various failure paths within their add routines. This creates the very fringe condition where the client was added, failed during add and didn't set the client_data. The core code will then still call other client_data centric ops like remove(), rename(), get_nl_info(), and get_net_dev_by_params() with NULL client_data - which is confusing and unexpected. If the add() callback fails, then do not call any more client ops for the device, even remove. Remove all the now redundant checks for NULL client_data in ops callbacks. Update all the add() callbacks to return error codes appropriately. EOPNOTSUPP is used for cases where the ULP does not support the ib_device - eg because it only works with IB.

2020-05-03RDMA/mlx5: Set lag tx affinity according to slaveMaor Gottlieb5-26/+71
The patch sets the lag tx affinity of the data QPs and the GSI QPs according to the LAG xmit slave. For GSI QPs, in case the link layer is Ethenet (RoCE) we create two GSI QPs, one for each physical port. When the driver selects the GSI QP, it will consider the port affinity result. For connected QPs, the driver sets the affinity of the xmit slave. The above, ensures that RC QP and it's corresponding GSI QP will transmit from the same physical port.

2020-04-29RDMA/mlx5: Change scatter CQE flag to be set like other vendor flagsLeon Romanovsky2-8/+10
In similar way to wqe_sig, the scat_cqe was treated differently from other create QP vendor flags. Change it to be similar to other flags and use flags_en mechanism.

2020-04-29RDMA/mlx5: Use flags_en mechanism to mark QP created with WQE signatureLeon Romanovsky3-16/+23
MLX5_QP_FLAG_SIGNATURE is exposed to the users but in the kernel the create_qp flow treated it differently from other MLX5_QP_FLAG_*s. Fix it by ditching wq_sig boolean variable and use general flag_en mechanism.

2020-04-29RDMA/mlx5: Process create QP flags in one placeLeon Romanovsky1-99/+101
create_flags is checked in too many places and scattered across all the code, consolidate all the checks inside one function, so we will be easily see the flow. As part of such change, delete unreachable code, because IB/core is responsible sanitize the input.

There is no point in redefinition of stable and exposed to users create flags. Their values won't be changed and it is equal to used by the mlx5. Delete the mlx5 definitions and use IB/core fields.
