Hi Stephen, Here the diff between logs:
# diff vfio.log xdp.log 7,11d6 < EAL: Using IOMMU type 1 (Type 1) < EAL: Ignore mapping IO port bar(2) < EAL: Probe PCI driver: net_e1000_igb (8086:1521) device: 0000:15:00.0 (socket 0) < EAL: Ignore mapping IO port bar(2) < EAL: Probe PCI driver: net_e1000_igb (8086:1521) device: 0000:15:00.3 (socket 0) 22,23c17,18 < Port 0 Link up at 1 Gbps FDX Autoneg < Port 1 Link up at 1 Gbps FDX Autoneg --- > Port 0 Link up at 10 Gbps FDX Autoneg > Port 1 Link up at 10 Gbps FDX Autoneg 36c31 < RX desc=512 - RX free threshold=32 --- > RX desc=0 - RX free threshold=0 40,41c35,36 < TX desc=512 - TX free threshold=0 < TX threshold registers: pthresh=8 hthresh=1 wthresh=16 --- > TX desc=0 - TX free threshold=0 > TX threshold registers: pthresh=0 hthresh=0 wthresh=0 46c41 < RX desc=512 - RX free threshold=32 --- > RX desc=0 - RX free threshold=0 50,51c45,46 < TX desc=512 - TX free threshold=0 < TX threshold registers: pthresh=8 hthresh=1 wthresh=16 --- > TX desc=0 - TX free threshold=0 > TX threshold registers: pthresh=0 hthresh=0 wthresh=0 I don't know why dpdk-testpmd (using xdp) reports 10 Gbps but NICs are 1 Gbs only... Ciao, Alessio
