  17           This makes MadWifi determine the needed bus based on the target
  18           hardware. This will generally work most of the time, but there are some
  19           cases where you need to override it.

 100           This code is takes a wandering minstrel approach. Wander around the
 101           different rates, singing wherever you can. And then, look at the
 102           performance, and make a choice. Note that the wandering minstrel will
 103           always wander in directions where he/she feels he/she will get paid
 104           the best for his/her work.

 106 config MADWIFI_RCA_ONOE
 107         bool "Use the Onoe rate control algorithm"
 108         help
 109           Onoe is a credit based RCA where the value of the credit is determined
 110           by the frequency of successful, erroneous and retransmissions
 111           accumulated during a fixed invocation period of 1000 ms. If less than
 112           10% of the packets need to be retransmitted at a particular rate, Onoe
 113           keeps increasing its credit point till the threshold value of 10 is
 114           reached. At this point, the current transmission rate is increased to
 115           the next available higher rate and the process repeated with credit
 116           score of zero. Similar logic holds for deducting the credit score and
 117           moving to a lower bit-rate for failed packet
 118           transmission/retransmission attempts. However, once a bit-rate has
 119           been marked as failure in the previous attempt, Onoe will not attempt
 120           to select that bit-rate until 10 seconds have elapsed since the last
 121           attempt. Due to the manner in which it operates, Onoe is conservative
 122           in rate selection and is less sensitive to individual packet failure.

 124 config MADWIFI_RCA_AMRR
 125         bool "Use the AMRR rate control algorithm"
 126         help
 127           AMRR uses Binary Exponential Backoff (BEB) technique to adapt the
 128           length (threshold) of the sampling period used to change the values of
 129           bit-rate and transmission count parameters. It uses probe packets and
 130           depending on their transmission status adaptively changes the threshold
 131           value. The adaptation mechanism ensures fewer failed
 132           transmission/retransmission and higher throughput by not switching to a
 133           higher rate as specified by the backoff mechanism. In addition to this,
 134           the AMRR employs heuristics to capture the short-term variations of the
 135           channel by judiciously setting the rate and transmission count
 136           parameters.
 137
 138 config MADWIFI_RCA_SAMPLERATE
 139         bool "Use the SampleRate rate control algorithm"
 140         help
 141           SampleRate decides on the transmission bit-rate based on the past
 142           history of performance; it keeps a record of the number of successive
 143           failures, the number of successful transmits and the total transmission
 144           time along with the destination for that bit-rate. Stale samples are
 145           removed based on a EWMA windowing mechanism. If in the sampling
 146           process, no successful acknowledgment is received or the number of
 147           packets sent is multiple of 10 on a specific link, it transmits the
 148           packet with the highest rate which has not failed 4 successive times.
 149           Other than that it transmits packets at the rate which has the lowest
 150           average transmission time.
