Hi Qiming & dpdk dev team:

This is JackyCT.Chen from Advantech, we have a question about E823 DPDK loopback testpmd  ,
Could you please give us some advice?

We bind the E823 and X710 devices with vfio-pci driver and execute the DPDK testpmd . (detail see attached files please)

However,  both E823  "link status : down and link speed : None" , we expected that "link status : up and link speed : 10 Gbps" .
Do you have any suggestions?

Testing procedure & result:
Platform : Moro City Reference Planform ICX-D  ~ CRB

l   On-Board : E823

l   Ext-PCIE CARD : PCIE-2230NP-00A1E ( Intel X710 )
