Hi,

I have applied these 5 patches to master on ubuntu 18.04LTS
The resulting binary gave server+client ipv6 *only* tunnel
over ipv4 network.  100% success

Using only: --server-ipv6 12fc:1918::10:186:0:0/112

I am sure buildbot runs more extensive tests than my single test
but I would be happy to ACK this if i could work out how to.

Thanks
