[dpdk-dev] pci-passthrough using vfio-pci

    I have a quad port X710 nic card, and trying to use two ports in a VM
using pci-passthrough and other two ports in the Host.

After doing pci-passthrough using vfio-pci, all the pci devices are showing
under devices handled by dpdk PMD.

But the dpdk initialization in the host is failing, because of resource
busy.
This is because, DPDK EAL is trying to initialize all PCI devices including
the ones that are binded to VM.

I am able to run dpdk application in the host, using EAL whitelist option
(by whitelisting the required two PCI devices) fine.

Is there any way , to run the dpdk application in the host without using
EAL whitelist option, in this scenario?

Regards
Harish
