Your problem could be that Olsrv2 has no way to detect the link
datarate... it normally can query the data through the nl80211
subsystem on Linux (for Wifi).

You could use the link_config plugin to set the incoming bitrate of
each link in the configuration file:

The link metrics represent the reciprocal throughput... or a value
proportional to the airtime used up by transmitting the data.

The path metric is the sum of the link values, so it represents the
total airtime used by the transmission over the network.
