I was more referencing the case where host can still receive from both
interfaces, i.e. it is switching from the GPRS link to the WLAN link,
but can still receive packets in the GPRS link after the transtion. It
would be annoying if the gateway would stop sending me packets while
it is doing the RR for my WLAN address, while it could still sent them
to my GPRS address, and get them through.

So I would propose that we could have option saying that if the
address_update list still includes the currently used address, but the
preferred address changes, then the currently used address is still
used to send traffic until the RR of the new preferred address is
done, and the new preferred address is used after the RR is
successful.
