What kernel?

All I am saying is that the 4GB limit in the spec is enough and we don't
need another mechanism on the wire protocol for that, as the bottleneck is
in another place.

As I said before, an API for delivering data to the app as soon as it is
received on the sctp chunks, ndata for interleaving and the change to the
a_rnwd handling would solve all the issues.

For the specific topic of this issue, the a_rnwd change is enough.
