Dear, I'm the new for using DPDK. I met the problem while trying to use pdump to capture the packet from my own application, but it bumps into some error as below. Do you have any suggestions?
[oai@localhost pdump]$ sudo ./dpdk-pdump -- --pdump 'port=0,queue=*,tx-dev=/tmp/tx.pcap,rx-dev=/tmp/rx.pcap' EAL: Detected 72 lcore(s) EAL: Detected 2 NUMA nodes EAL: Multi-process socket /var/run/dpdk/rte/mp_socket_10018_2d422b12bdfd4 EAL: failed to send to (/var/run/dpdk/rte/mp_socket) due to Connection refused EAL: Fail to send request /var/run/dpdk/rte/mp_socket:bus_vdev_mp vdev_scan(): Failed to request vdev from primary EAL: Selected IOVA mode 'VA' EAL: Probing VFIO support...

The DPDK version in our lab is for 19.11. After modifying CONFIG_RTE_LIBRTE_PMD_PCAP=y & CONFIG_RTE_LIBRTE_PDUMP=y,I try to use ICC for the compilation. Also, I already add function rte_pdump_init() in my application. Best Regards, Shu-hua, Liao
