Hello, I believe I have setup my environment to support SR-IOV. I am not sure
why the system creates a linux bridge when you setup and bind a VM network to a
virtual function on the NIC.
I have 2 VLANs 102 and 112 however, there are linux bridges now setup.
I would assume with SR-IOV the VF would be connected only to the VM.
