Just one more piece to clarify... in the general case (e.g inner
packet size 1.5k...64k), the last segment would not have the same
length as the other segments, what happens on that case?

Actually in the case of GSO partial we have go through the software
segmentation code and trim off any last bit that doesn't match the MSS
of the rest of the frame.  That way you end up with one frame that has
some number of MSS sized chunks, and then one remainder if there is a
frame that would be a different size.

OK, thanks for further clarifying this, will look on the docs you 
pointed etc. From what you wrote here I understand it's indeed possible 
for one frame to be of different size from the rest, but the LCO thing 
still works somehow..

Or.
