How to add packet capture framework to a custom simple dpdk app

[Fuji Nafiul]

Hi,
I am using dpdk_v22.11.1 on ubuntu_v22.04.2. I have a simple app derived
from skeleton and icmpecho which can reply to proper arp requests and also
can reply to appropriate pings. Now whats the proper steps to add a packet
capture framework like dpdk-dumpcap here as the doc didnt clearly said it,
rather pointed out to check the testpmd.c

I simply added pdump header files, then initialized rte_pdump_init(), then
I tried to run dpdk-dumpcap separately that was successful after running
testpmd app but with my custom app it  failed.to run Then I
noticed configure_rxtx_dump_callbacks() in port initialization and tried to
add it properly in my app but failed. I am just not sure whether I am on
the right way or not. so please help if you have already passed this.
thanks in advance..!
