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 ?


Best Regards,
Shu-hua, Liao
