The socket must have an association. That is, the socket FD must either be
returned by ext_accept() or an association has been established by
ext_connect().

Note, that the size of the receive and send buffer are currently specified in
chunks, not bytes. This is due to the sctplib's implementation. 0x80000 =
524288 chunks seems to be quite large.
