git bisect came up with the following:

# first bad commit: [830e3de48a789f8d294a0d1461600f958afddde4]
ip6_gre: skb_push ipv6hdr before packing the header in ip6gre_header

However, reverting this commit didn't work either. I might have to
start bisect again. Update for now in case David or Xin Long can
think of something that could possibly lead this failure. There are
a few more patches in this space.
