Hi All,

Can anybody guide me I am unable to run dpdk-dumpcap application with dpdk-22.03 ,

I am performing following steps:

First:

$ sudo ./build/app/dpdk-testpmd -l 0-3 -n 4 -a 0000:04:00.1 --proc-type=primary -- -i --rxq=8 --txq=8

Second:

$ sudo ./build/app/dpdk-dumpcap -i 1 -c 6 -w /tmp/capture.pcapng

I am getting following error
