IB/mlx4: Optimize QP stamping
The idea is that for QPs with fixed size work requests (eg selective signaling QPs), before stamping the WQE, we read the value of the DS field, which gives the effective size of the descriptor as used in the previous post. Then we stamp only that area, since the rest of the descriptor is already stamped. When initializing the send queue buffer, make sure the DS field is initialized to the max descriptor size so that the subsequent stamping will be done on the entire descriptor area.
