We have two modems for each node and in one of them, expected throughput should be about 6 Mb/s for example, and in the other one it should be about 30 Mb/s. By using iperf and also throughput meter I can see that it's the case. But when they are added to batman with batctl if add, after typing batctl o, I see that the throughput values in both interfaces are 10000 instead.
I looked at the interfaces with ethtool and the speed is 10000 Mb/s there for both too which is how batman must be measuring the throughput but this isn't good because it doesn't reflect the actual speed. If we use throughput override, it's fine at first but one of the modems has a shorter range so in our test where two nodes move away from each other, actual throughput gets decreased due to losses but batman still chooses the same interface due to the overriden value.
Basically I would prefer batman being able to change measured throughput dynamically.
