I believe even the registration part should belong to kernel and here are the reasons why. The Home Agent needs to consult the Binding Cache, which is stored upon successful completion of Binding updates registration, for tunnelling the packets belonging to the mobile nodes away from home. In addition, as part of the registration process but before caching the binding updates, the Home Agent may need to perform duplicate address detection (DAD), if needed, through ND protocol messages. And also, IPSec is mandated for Home Agent registration and so, Home Agent must use IPSec for responding to Binding updates from Mobile Nodes.
