Do you have any pointer for me where this is defined? Why is it needed, given that GCM implicitly authenticates the IV by using it in Y0? Also, I've just verified that a tunnel between the Windows Filtering Platform and Linux 3.13 using AES128GCM16 works just fine. So if we do something wrong, the problem does not only affect Linux.
