Lines Matching defs:rack
122 * - The number of unacknowledged xmit packets is (ns - rack) <= seq->wmax
123 * - The first (ns - rack) mbuf's in xwin[] array are copies of these
127 * Therefore, (i < cwnd && xwin[i] != NULL) implies (ns - rack) > i.
128 * - rack_timer is running iff (ns - rack) > 0 (unack'd xmit'd pkts)
