[dpdk-users] Link Status Down on Cisco C220 M3 Enic Driver

[Haci Burak]

Hello ,

I am new to DPDK and I have this problem with the link status. But when i
see it with CIMC their status is up and actually both interface is
connected to each other with cable.
I have followed the instructions and here my logs and outputs is below. If
there any other logs or stats i can provide ,  i would gladly do that. I am
trying to run on host machine installation. (No VM )
