Zero ports detected issue for Solarflare (SFC9250) cards

[avatli at itu.edu.tr]

Hi all

I'm trying to use Solarflare (SFC9250) cards with DPDK. I have  
compiled the skeleton/basicfwd application but when I run it with the  
following parameters, the number of ports becomes zero, and it can't  
detect the Solarflare ports on the system.

$ sudo examples/dpdk-skeleton -l 0 -n 2
EAL: Detected CPU lcores: 10
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'
TELEMETRY: No legacy callbacks, legacy socket not created
EAL: Error - exiting with code: 1
   Cause: Error: number of ports (0) must be even

Currently, the platform is using dpdk-stable-22.11.2 and CentOS 7

What am I doing wrong? I would greatly appreciate your assistance
