Hi, all

 

I¡¯m doing experiments with OVS and OVS DPDK, only one bridge is there,
ports and flows are same for OVS and OVS DPDK, in OVS case, everything works
well, but in OVS DPDK case, iperf udp performance data are very poor, udp
packets are out of order, I have limited MTU and send buffer by ¨Cl1410 ¨C
M1410, anybody knows why and how to fix it? Thank you in advance.
