Then the problem is on the other end. The selector either says every 
packet _MUST_ be IPsec-protected or else it _MUST NOT_ be IPsec-protected.
Either way, if some packets--those with Binding Updates-- are received with
IPsec protection and others-- those without Binding Updates-- are not then
we're going to have a problem.
