Hi VPP developers,

I am new to VPP and we want to add support of some Cavium NICs/non-NICs in VPP. 
Our existing custom user space PF driver has VFIO NO IOMMU support to get MSIX 
interrupts from device. It seems VFIO support in VPP can be used via dpdk only. 
So my question

1) Is there any plan to add vfio support in VPP itself like UIO in future?

2) Is it allowed to upstream non-NIC/PF user space driver in VPP? As it seems 
dpdk do not allow PF user space drivers to upstream into dpdk. Also in dpdk 
currently lacks non-nic support (like librte_crypto)


Thanks,

Nitin
