Comment 8 for bug 1478924

7.0 and above has two segmentation types: 'vlan' and 'tun'
'tun' means a 'vxlan'. Also has workaround 'gre' for use deprecated, unrecommended to use 'gre' segmentation.

I propose leave it as is, because we going to deploy both segmentation (tun and vlan) cases simultaneously. VXLAN will be used for this case as tun.
