I think these should be new attributes to RTM_*LINK.
No need to define a new message.

   Is there a better way to get this information via netlink or some
   ioctl()? Would it be useful if I (or someone) added an ioctl() type to
   get information about a VLAN interface? (vlan, ifindex of trunking
   (real_dev) interface, priority maps; basically the content of struct
   vlan_dev_info)

I would accept new netlink interfaces to get and set this
information.  ioctls are gross and will not be tolerated :)
