Really. Well, that is odd. Are you working from the master branch?
I don't have a 4.5 kernel handy
but I can certainly check against the 4.4 kernel on Ubuntu 16. I'll go
see if something has broken.
It seems to be working for me on Ubuntu 16.04 with the 4.4-116 kernel.

Machine A can ping Machine B over the ip6gre tunnel:

PING 171.31.1.51 (171.31.1.51) 56(84) bytes of data.

So at least for Ubuntu 16.04 with the generic 4.4-116 kernel things are
working. Let me download and install
Fedora 24 and try that.
