We want to use precise timestamps in TCP stack, but we do not want to call possibly expensive kernel time services too often. tp->tcp_mstamp is guaranteed to be updated once per incoming packet. We will use it in the following patches, removing specific skb_mstamp_get() calls, and removing ack_time from struct tcp_sacktag_state.
