I have already tried that, it was one of the first things I tried, just looking over the git log and looking for usual suspects.
Sadly it has no effect whatsoever, the problem persists :(

Hehe now we're talking :D
I did something similar before, I think just switching a different bit every 10 packets or so and running a persistent ping until it succeeds or not.
I'll see what I can come up with.
