at the very moment for getting data from minstrel which should

We need the effective tx_goodput, what can be e.g.

55.1mbit (MCS15/SGI/HT40) which is only
= 18% of theoretical max = 300 mbit) and
= 13% of theoretical max using netperf TCP

A fast hack could be to implement new fields in debugfs like:


cool would be an event based hook, so olsrd receives updates, when
minstrel detects a change (threshold based ofcourse)

at the moment we have "only" a humanreadable output at:
