Maxime,
It won't be much performance difference between non-vectorized and vectorized.
The reason to add special vectorized version is for skipping the handling of garbage GSO packets. 
As all descs have been handled in batch, it is needed to revert when found garbage packets. 
That will introduce complicated logic in vectorized path.

Marvin
