The issue is that the Virtual Function / Physical Functions have setup the internal virtual switch to only route Ethernet packets with destination MAC address matching the VM virtual interface MAC. How can I configure my virtual environment to provide all network traffic to the VM...i.e. set the virtual functions for both PCI devices in Promiscuous mode?

This is a host side (not DPDK) issue.
Intel PF driver will not allow guest (VF) to go into promiscious mode
since it would allow traffic stealing which is a security violation.
