 * -----------------------       ---------------
 * 0x00000000...0x0000feff  <=>  0x0000...0xfeff  "physical" ports
 * 0x0000ff00...0xfffffeff  <=>  not supported
 * 0xffffff00...0xffffffff  <=>  0xff00...0xffff  "reserved" OFPP_* ports
 *
 * OFPP11_OFFSET is the value that must be added or subtracted to convert
 * an OpenFlow 1.0 reserved port number to or from, respectively, the
 * corresponding OpenFlow 1.1 reserved port number.
