RDMA/mlx5: Set lag tx affinity according to slave
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.
