Having done no work in this area for over a decade.... I think that the GSO
marking is in the skb (which is a Linux-ism, obviously), which goes down into
the device-specific driver, who then loads the single packet into the device
queue, and marks the packet for GSO in a device-specific way in the ring
descriptor.

The device does the Segment Offload.  There is no marking relevant in the
packet itself. There aren't multiple skb's for the packet.

So I think that the answer is "mu"
