mi-mctp info reports SMBus instead of expected USB port #6
Description
Running the mi-mctp info command, the results show two ports: one PCIe and one SMBus. I believe the output should be PCIe with USB.

Unfortunately, there is no port type representation for USB (see secton 5.7 .2 of the NVMe-MI spec)
