Is there a shell command to show a port’s status, such as link status and port ID etc.  For non-DPDK bound port I can use tools like “ifconfig”.  Does DPDK provide an “ifconfig” equivalent tool to check a port status?

    Read about KNI. but if all you want is port status, then it would be overkill.
