Privacy Label Computation
HoA should be recoverable from the Label

Label should be computable without HoA, since HoA should not be visible in any route-optimized packets (including BU) sent from the MN to CN

If BU is reverse-tunneled, the HoA is visible in the HA – CN path, but Label computation can include HoA

If BU is sent route-optimized, HoA is not visible at all, but needs addition of a bit to the HOTI message
