Re: [dpdk-users] port 0 not present on board error

[Pragash Vijayaragavan <pxv3620@rit.edu>]

I tried to debug by printing the check_port_config function

and printed the nb_ports parameter, -> this is 0

so i guess no ports are bind to the dpdk driver since its still showing
net_i40e in probe driver.

Should i do any config to solve this error.
i am using igb_uio and the ports are bind correctly, i bind using the
dpdk_dev_bind script.
