An Infiniband port requires client ID, while local link connection information will
be populated by Infiniband Subnet Manager.
The client ID consists of <12-byte vendor prefix>:<8 byte port GUID>.
There is no standard process for deriving the port's MAC address ($HW_MAC_ADDRESS);
it is vendor specific.
For example, Mellanox ConnectX Family Devices prefix is ff:00:00:00:00:00:02:00:00:02:c9:00.
If port GUID was f4:52:14:03:00:38:39:81 the client ID would be
ff:00:00:00:00:00:02:00:00:02:c9:00:f4:52:14:03:00:38:39:81.
Mellanox ConnectX Family Device's HW_MAC_ADDRESS consists of 6 bytes;
the port GUID's lower 3 and higher 3 bytes. In this example it would be f4:52:14:38:39:81.
Putting it all together, create an Infiniband port as follows::
openstack baremetal port create $HW_MAC_ADDRESS --node $NODE_UUID \
--pxe-enabled true \
--extra client-id=$CLIENT_ID \
--physical-network physnet1
#. Check the port configuration::
openstack baremetal port show $PORT_UUID
