- * It is important to realize that "recovery" mode starts after failure of
- * the first transmission after a rate increase and ends at the first successful
- * transmission. Specifically, recovery mode transcends retransmissions boundaries.
- * Fundamentally, ARF handles each data transmission independently, whether it
- * is the initial transmission of a packet or the retransmission of a packet.
- * The fundamental reason for this is that there is a backoff between each data
- * transmission, be it an initial transmission or a retransmission.
