I meant his first initial patch :)

While it is suboptimal in the sense that should the value of
needed_headroom increase we'll end up constantly reallocating
skbs, I believe that it is at least semantically correct.

In the time being I'll look more closely at all the users of
needed_headroom to see if there's anything we've missed.

Thanks,
