An SR-IOV NIC
I was using an Mellanox ConnectX-3. Instructions for configuring this can be found here.
Two tweaks are necessary to use this.
enp2s0 with the netdev name of your PF.enp6s0 with the netdev name of the device you wish to use with OVSThis is based on the sample local.conf provided in a Mellanox presentation
