Section 4.3 says:
The QS Nonce in the Response is set to the received value of the QS Nonce in the Quick- Start Option.
It should say:
The QS Nonce in the Response is set to the received value of the QS Nonce in the Quick- Start Option. If the TCP host has sufficient receive buffer space, it could estimate the required buffer space as the product of the approved Quick-Start rate and the round-trip time, and advertise a receive window based on this required buffer space. This receive window should allow the other TCP host to fully use the approved Quick-Start Request. If the TCP host doesn't know the round-trip time, the TCP host could use an estimate of the round-trip time in calculating the required buffer space. Alternately, the TCP host could base the advertised receive window on the available buffer space, without calculating the buffer space required for the other TCP host to fully use the approved Quick-Start Request. If the Quick-Start Response is sent in a SYN/ACK packet, then window scaling of the receive window is not allowed [RFC1323]; if necessary, the TCP host could send a scaled receive window in a separate ACK packet following the SYN/ACK packet.
Clarification regarding the receive window.
