Thanks!
We might simplify this further. Just reset the first two fields flags
and gso_type.

What's this "simplification" for? Don't even to say that we will add
TSO support, which modifies few more files, such as csum_start: reseting
the first two fields only is wrong here.

I know TSO before commenting, but at least in this implementation and
this specific patch, i guess zeroing two fields are enough.

What is wrong resetting only two fields?
