Subject: RE: [PATCH net-next] net: Add phys_port identifier to struct
 net_device and export it to sysfs

Having an unique identifier per port, the userspace tools might be able to check if the VFs/partitions are of the same physical port. Just being paranoid, wouldn't it be better to bond VFs/Partitions across NICs instead of across ports of the same NIC?

To be able to check if the VFs/partitions are of the same port & NIC, the unique identifier should probably have two identifiers  in it like ABC_XYZ. The ABC uniquely identifying the NIC and XYZ uniquely identifying the port.   

Any thoughts?

Thank you
