Can you please make the function static?

It is very unlikely that it will fail but still it can be good add the return 
value check
   if (rte_eth_dev_info_get(port_id, &dev_info) > 0)
     device_infos_display_speeds(dev_info.speed_capa);

Is the 'speed_capa' variable still needed? Why not directly use 
'dev_info.speed_capa'?

If function becomes static this deceleration won't be needed.
