Not that obvious...
skb->next is cleared in lots of places, in xmit network helper
for example, but since rest of the packet was not modified, it
means given skb was not freed, so it will not help.

Ingo do you see other similar dumps with last byte modified?
That's the one which can help to determine the reason.
