What type of tanha, is the tanha to end tanha?

This is from the Bhikkhuni Sutta AN 4.159 "Taṇhā sambhuto ayaṃ bhagini kāyo, taṇhaṃ nissāya taṇhā pahātabbā" "'This body, Sister, comes into being through craving. And yet it is by relying on craving that craving is to be abandoned.' (Translation from Access To Insight) Now this tanha, is it a kaama tanha, bhava tanha, vibhava tanha, any of them, or something other than them? This is more of an academic question so, please answer when time permits. Thank you in advance. With metta.
