What metric are you using ? etx_ff should be a little bit more tame than

You don't need to remove anything, because the "dijkstra hysteresis" is
controlled by the routing metric plugin too (there should be a callback called
"is....relevant(linkcost1, linkcost2)" ).
Markus Kittenberg played with the idea of a "long time" metric for some time,
but we never got enough time to create a good plugin. We would be very happy
to see a suggestion for an improved etx_ff. :)
