In order to track CE marks per rate sample (one round trip), TCP needs a per-skb header field to record the tp->delivered_ce count when the skb was sent. To make space, we replace the "last_in_flight" field which is used exclusively for NV congestion control. The stat needed by NV can be alternatively approximated by existing stats tcp_sock delivered and mss_cache. This patch counts the number of packets delivered which have CE marks in the rate sample, using similar approach of delivery accounting.
