Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/neutron" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

Change tunnel MTU calculation to support IPv6
The IPv6 header is twice the size of the IPv4 header, 40 vs 20
bytes, but the tunnel overhead constants are static, only
accounting for an IPv4 header in all cases. In order to be
correct it needs to treat the tunnel overhead different from
the IP overhead at L3.
This required removing the 20 byte IP overhead from the tunnel
type overhead constants and creating a new option,
ml2.
version will be used, since it calculates the MTU for the network.
A version mis-match will now cause a tunnel sync to fail on
the server.
Moved all MTU tests to a common location to remove duplication.
