Having in mind that throughput and bandwidth are not the same and do not necessarily match; the use of the word "throughput" in batman-adv (Layer2)
is misleading and can cause confusion when in measuring the real throughput on layer3 with L3 software.
As far as i know; at the moment batman-adv (L2) has no way to know what is the real throughput that the announced gateway bandwidth (l3) actually allows therefore the "
throughput" should be changed to announced bandwidth.
Example:
If the node is a gateway client the parameter will decide which
criterias to consider when the batman-adv module has to choose
between different internet connections announced by the afore-
mentioned servers.
default: 20 -> late switch (TQ 20)
examples: 1 -> fast connection
consider the gateway's advertised
bandwidth as well as the link quality
towards the gateway and stick with the
selection until the gateway disappears
2 -> stable connection
chooses the gateway with the best link
quality and sticks with it (ignore the
advertised bandwidth)
3 -> fast switch connection
chooses the gateway with the best link
quality but switches to another gateway
as soon as a better one is found
XX -> late switch connection
chooses the gateway with the best link
quality but switches to another gateway
as soon as a better one is found which
is at least XX TQ better than the cur-
rently selected gateway (XX has to be a
number between 3 and 256).

Yeah, batman-adv does not know anything about the real throughput.

I think this change is correct. Why not sending a patch that we can directly
apply in the batctl repository?
Thanks.
