Detailed Description

struct dccp_ackvec - Ack Vector main data structure

This implements a fixed-size circular buffer within an array and is largely based on Appendix A of RFC 4340.

: circular buffer storage area : head index; begin of live portion in : tail index; first index after the live portion in : highest seqno of acknowledgeable packet recorded in : lowest seqno of acknowledgeable packet recorded in : ECN nonce sums, each covering subsequent segments of up to DCCP_SINGLE_OPT_MAXLEN cells in the live portion of : if 1 then buf_head == buf_tail indicates buffer wraparound : list of dccp_ackvec_record (Ack Vectors sent previously)
