   I've been working with Bastien in the Matrix Debian room today on making   
   a reproducer for this. I've successfully done that using two debvm   
   stable/trixie images linked together via two host TAP interfaces.   
      
   With v6.12.63 a ping between the two VMs using their GRE addresses   
   works; for v6.12.69 it does not.   
      
   Analysing packet flow shows the GRE packets arrive on the VM's Ethernet   
   interface but does not get decapsulated to the ip6gre tunnel interface.   
      
   I read through the commits between the two during the day and have   
   identified several suspects.   
      
   I've just started bisecting and building test kernels and will report   
   back later.
