OK, I agreed.

But simply adding another name and attribute also means that a VXLAN
interface can have multiple "last resort".
So I'll try to fix as below:

  1) Replace "gaddr" by "daddr", in struct vxlan_dev.
  2) Add IFLA_VXLAN_REMOTE apart from IFLA_VXLAN_GROUP.
  3) If IFLA_VXLAN_REMOTE and IFLA_VXLAN_GROUP are specified at a
     time, vxlan_validate() will return an error.

If you have other better ideas, please let me know.

Thanks.
