[pve-devel] [PATCH ifupdown2] d/patches: add patch for adding IPv6 vxlan-local-tunnelip

[Gabriel Goller]

Just to keep the mailing list in the loop:

* when installing the packet the following error is visible: 

     find: ‘/var/lib/dhcp/’: No such file or directory

     but I didn't notice anything off, so probably a debian packaging
     thingy.

* when using a vxlan interface with a ipv6 tunnelip the reload fails:
     config:

     auto vrfvx_zone
     iface vrfvx_zone
             vxlan-id 101
             vxlan-local-tunnelip fc00:10::2
             bridge-learning off
             bridge-arp-nd-suppress on
             mtu 1450

     error:

Thanks for rebasing this!
