The command\nexample is like:\n\nFor displaying a specific port stats (e.g. port 1):\n./dpdk-proc-info -- --show-edev-port-xstats=1:0\n\nIf any xstats parameters for eventdev passed through\nproc-info command line, proc-info will only display\nrequested eventdev data and exit.\n\nUsers should not pass any eventdev xstats parameters\nif they desire to dump other proc-info data such as\nRx/Tx descriptor dump.\nMore information can be found in proc-info app doc.\n\nSigned-off-by: Abdullah Sevincer <abdullah.sevincer@intel.com>\n---\n app/proc-info/main.c | 297
