2020-05-06RDMA/hns: Optimize WQE buffer size calculating processXi Wang3-265/+182
Optimize the QP's WQE buffer parameters calculating process to make the codes more readable mainly by merging calculation of extended sge space of kernel and userspace. In addition, add some inline functions to simply codes about multi-hop addressing.

2020-05-06RDMA/hns: Remove unused MTT functionsXi Wang6-807/+2
The MTT (Memory Translate Table) interface is no longer used to configure the buffer address to BT (Base Address Table) that requires driver mapping. Because the MTT is not compatible with multi-hop addressing of the hip08, it is replaced by MTR (Memory Translate Region) interface, and all the MTT functions should be removed.

PBL table has its own implementation for multi-hop addressing currently, but for the hardware, all table's addressing use the same logic, there is no need to implement repeatedly.

2020-05-02RDMA/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.
