Hi Asaf,
Please see details, let me know if more details required.
What DPDK version do you use?
DPDK-20.05
What EAL and devargs value are being used?
Following are the argv at eal_init
1005 if (rte_eal_init(argc, argv) < 0)
(gdb) p argv
$7 = {0x72bce60 "fast_pkt_app", 0x72bce90 "-c 6c", 0x72bcec0 "-m 1024", 0x72bcef0 "-n 1", 0x72bcf20 "--file-prefix=gnb_du_rte_config", 0x72bcf50 "--proc-type=auto", 0x72bcf80 "-w0000:c1:00.0",
0x72bcfb0 "-w0000:c1:00.1", 0x72bcfe0 "", 0x72bd010 ""}
