As pointed out by Fernando Gont there is no need to encode rcv_wscale into the cookie. We did not use the restored rcv_wscale anyway; it is recomputed via tcp_select_initial_window(). Thus we can save 4 bits in the ts option space by removing rcv_wscale. In case window scaling was not supported, we set the (invalid) wscale value 0xf.
