Hope the 3 combinations can support the claims in the commit message.
Since for the later 2 combinations, due to packet dropping and timeout-retransmission, the bandwidth of each TX node could suddenly drop a few hundred MB/S. And on the RX node, the total bandwidth can not reach to the full link bandwidth (which is about 6 GB/S). . In contrast, for the first combination, the bandwidth of each TX node is stable at ~ 2GB/S. And on the RX node, the total bandwidth reached to the full link bandwidth. And no packet dropping occurs on the 2 switches. This is even competitive to the performance of RDMA.
