This output shows the first eight cards are configured for InfiniBand and correspond to
the network cluster ports. The last card has two ports which correspond to the two
network storage ports. These are configured for Ethernet should not be changed.
Map the Device bus numbers from your output to the device name from the mst
status output on your system. For example, this example output shows that the
device name for bus bd is /dev/mst/mt4119_pciconf5. You will need the device
name when changing the configuration.
