IPoIB: Double default RX/TX ring sizes
Increase IPoIB ring sizes to twice their original sizes (RX: 128->256, TX: 64->128) to act as a shock absorber for high traffic peaks. With the current settings, we have seen cases that there are many calls to netif_stop_queue(), which causes degradation in throughput. Also, larger receive buffer sizes help IPoIB in CM mode to avoid experiencing RNR NAK conditions due to insufficient receive buffers at the SRQ.
