Hi, I used af_packet interface, but found only can send packets successfully less than framecnt argument.
E.g. if I pass "--vdev=eth_af_packet0,iface=tap0,blocksz=4096,framesz=2048,framecnt=512,qpa irs=1,qdisc_bypass=0" to DPDK, the rte_eth_tx_burst only return 1 for 512 times, after that it always return 0. If I pass "--vdev=eth_af_packet0,iface=tap0,blocksz=4096,framesz=2048,framecnt=1024,qp airs=1,qdisc_bypass=0" to DPDK, the rte_eth_tx_burst only return 1 for 1024 times, after that it always return 0. BTW, I use busy loop mode in project, Is there any help for this? Thanks so much Haifeng
