16 Since the mid-2010s, network cards have started offering more complex
17 virtualisation capabilities than the legacy SR-IOV approach (with its simple
18 MAC/VLAN-based switching model) can support. This led to a desire to offload
19 software-defined networks (such as OpenVSwitch) to these NICs to specify the
24 virtual switches and IOV devices. Just as each physical port of a Linux-
