[dpdk-dev] DPDK Performance issue with l2fwd

Hi Bruce: Thanks for your reply so much. All my test are using 1518 byte packets and keep the criteria which I told before due to I need to know how many Gb can be handle in our platform. Originally, I think it should no any limitations in DPDK. But, it seems a little surprised for me when I get

I just upgraded my kernel to 3.15.5 and hardcoded below captured from include/uapi/linux/if_packet.h to librte_pmd_packet.c to workaround it, now I can receive/transmit packet now. Commenting out PACKET_FANOUT_FLAG_ROLLOVER would cause no packet can be received. #define PACKET_QDISC_BYPASS
