The basic features for operating floating VEB over Mellanox adapters exist:
- We support SR-IOV VFs on a Mellanox adapter "binded" to VMs, thus, enabling local traffic between the VMs
- VFs can be up inspire of the physical NIC being down (no link connection outside) and traffic from VF to VF runs even when the physical link is down
- local switching between virtual endpoints within a physical endpoint can be implemented and remains within the host.
