Regarding Netmap in VM

Suppose I am on x86 with Intel 82599 NIC.
Now I spawn a VM (running FreeBSD as guest OS with Netmap support)
For better I/O performance, I have two main choices --

1. Pass the 82599 NIC as a PCI passthrough device into the VM
2. Use SRIOV VF of 82599 into the VM

Question is, will Netmap be able to utilize both the above environments
when I run the userspace application in the guest OS in the VM, or will
there be any issues.
