I agree with Vladimir, this looks quite a bit too complex for a net fix
at this late point of the cycle. Given the period of the year, I think
it could be too late even for net-next - for this cycle.

It would be great if you could add some self-tests.

@Faizal: I understand your setup is quite complex, but it would be
great if you could come-up with something similar that could fit 
tools/testing/selftests/net

Thanks!
