Right, retransmission rate or error rate might be helpful to add. A number of
questions still need to be answered:

* Is this information exported by Wifi drivers like ath9k/ath10k/others ?
* How is this information factored into the equation ?
* How does the result compare to the actual throughput ?

Especially the last point is somewhat crucial simply because in a mesh network
with a healthy mix of devices & drivers all these various sources of
throughput data need to be comparable. Picture a situation in which batman-adv
needs to choose a route involving Ethernet throughput / manual throughput /
expected throughput / bitrate throughput.

Cheers,
Marek
