(2) Don't set the reference serial number in a delayed ACK as the ACK cannot be used for RTT calculation. (3) Don't emit a DUP ACK response to a PING RESPONSE ACK coming back to a call that completed in the meantime. (4) Fix the counting of acks and nacks in ACK packet to better drive congestion management. We want to know if there have been new acks/nacks since the last ACK packet, not that there are still acks/nacks. This is more complicated as we have to save the old SACK table and compare it. ==================== Signed-off-by: David S. Miller --- 645eb54331edb0dc0297c7e37162a3846bf99300
