Your idea of using skb_segment to remove duplicate code is great.

However, using skb->gso_skb for the push-back doesn't work.  For
example, what is going to happen when I enable software GSO on a
wireless device and then send a real GSO packet to it where each
GSO fragment also required wireless fragmentation?

I suggest that you just use skb_segment for the actual fragmentation
but keep the original infrastructure for handling the fragments.

Cheers,
