You can do it, but since port names are immutable it has to happen at
the time you add the port.  For example:

blp at sigabrt:~/nicira/ovs/tutorial(0)$ ovs-vsctl add-br br0
blp at sigabrt:~/nicira/ovs/tutorial(0)$ ovs-vsctl add-port br0 p0 -- set port p0 name=asdf
blp at sigabrt:~/nicira/ovs/tutorial(0)$ ovs-vsctl show
8b75cccb-f1eb-4e75-ac67-57ebac4e8432
    Bridge "br0"
        Port "br0"
            Interface "br0"
                type: internal
        Port asdf
            Interface "p0"
blp at sigabrt:~/nicira/ovs/tutorial(0)$
