Wendy, the problem Markus stepped on was no GRO on the receive side b/c
of bad ID-ing of packets on the sender side during the TSO process.
GSO is SW TSO, has nothing to do with GRO.
The code you referred two probably protects against an skb attempting to
go through both TSO/GSO and GRO
(e.g on forwarding) which isn't the case here.
