Dear Stephen, Thanks for your response !!! Yes, I already set *CONFIG_RTE_LIBRTE_PMD_PCAP=y *and *CONFIG_RTE_LIBRTE_PDUMP=y *in the file "dpdk-19.11/config/common_base" then build DPDK. Also, in the files "dpdk-19.11/x86_64-native-linuxapp-icc/.config" and "dpdk-19.11/x86_64-native-linuxapp-icc/.config.orig", they also show that *CONFIG_RTE_LIBRTE_PMD_PCAP=y *and *CONFIG_RTE_LIBRTE_PDUMP=y.*
It seems that it already enabled pcap PMD of DPDK. Do you have other suggestions ?
