The mlx4 driver uses a special QP to implement the GSI QP. This kind of QP allows to build the InfiniBand headers in software. When mlx4 hardware builds the packet, it calculates the ICRC and puts it at the end of the payload. However, this ICRC calculation depends on the QP configuration, which is determined when the QP is modified (roce_mode during INIT->RTR). When receiving a packet, the ICRC verification doesn't depend on this configuration. Therefore, using two GSI QPs for send (one for each RoCE version) and one GSI QP for receive are required.
