rx_priv_buf_alloc is used to tell hardware how much buffer is used for rx direction, right now only the private buffer is assigned. For ae_dev that doesn't support DCB, private rx buffer is assigned to zero, only shared rx buffer is used. So not setting the shared rx buffer cause dropping of packet in SSU.
