When segmenting a GSO packet, the IP header is copied to all segments.
The code has grown quite complex over the years, but it's easier to see
in the original submission from 2006:
https://lore.kernel.org/all/20060622081400.GC22671@gondor.apana.org.au/
Which means all packets in a GSO segment will end up marked on the
wire...
