Well, we hit the dummynet case for sure and should get the proper 
interface pointer from the packet tag. Nothing changed with the 
processing there. The only change I found is, that the presents of a 
dummynet tag in ip_output previously reset flags, which is no longer that 
case. Can you try attached patch to see if that is the issue (from 
reading the code I don't really hope that this will be it, but it's the 
only thing I can come up with atm, sorry.)
