an implementation of the AARF-CD algorithm
This algorithm was first described in "Efficient Collision Detection for Auto Rate Fallback Algorithm". The implementation available here was done by Federico Maguolo for a very early development version of ns-3. Federico died before merging this work in ns-3 itself so his code was ported to ns-3 later without his supervision.
ns3::AarfcdWifiManager is accessible through the following paths with Config::Set and Config::Connect:

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.
