For every HCA, one physical data link per port is created by default. You can use the physical links as administrative and observable data points. You can create IB partition links over the physical data links, similar to a creating VNICs over a NIC. Because physical data links are not used for data transfers, plumbing and assigning IP addresses is not supported on these links. Data is transferred on the partition data links.
