ovs-ofctl doesn't support 32-bit port numbers.  That's not a problem for
interacting with Open vSwitch as a switch, since Open vSwitch always
assigns port numbers in the 16-bit range.  It might be a problem if you
are using ovs-ofctl with some other OpenFlow switch that has
high-numbered ports; sorry.
