Minor nit, otherwise good to go.

Common IB HCA models (e.g. Mellanox ConnectX 7) can operate in either InfiniBand mode or Ethernet mode. When operating in Ethernet mode, they are still reported in
/sys/class/infiniband, but have a LinkDown physical status. Thelink_layerproperty can be used to determine which ports are InfiniBand vs Ethernet.
