I am surprised you still are configuring a throughput override of 100kbit/s. What's the idea behind this configuration ?
I have two channels between nodes (actually more, but this doesn't matter now) 1) Radio modem, connects as follows: NODE1(eth0)<-->modem(radio)<-->(radio)modem<-->(eth0)NODE2 eth0 interface have 100mbit/s speed and batman detects it as 100mbit/s. radio has 145kbit/s, and actual speed of this channel is 145kbit/s
2) eth1 Ethernet channel. Speed of this channel is 100mbit/s NODE1(eth1)<---->(eth1)NODE2
Now make a test: 1) Set up eth0 modem channel 2) Disconnect eth1 channel 3) Turn on nodes - batman saw eth0 channel between nodes and detected speed 100mbit/s (because speed between node and modem is 100mbit/s, as I understand) 4) plug eth1 cable in - At this moment I expect batman switch to eth1 channel because it has real 100mbit/s speed. But batman doesn't switch, because it detects eth0 as 100mbit/s too. Therefore I override throughput of eth0, actually batman detects incorrect speed on eth0.
