I don't understand what you mean by 'the "new" netlink interface'. You can create a PPP interface either with the PPPIOCNEWUNIT ioctl or with netlink. But no matter how you create it, you need a /dev/ppp file descriptor associated to the PPP network device. Other than that, and no matter how you create them, PPP network devices can be used and configured like any other network interface. You absolutely can use "ip link" to manage you ppp interfaces.
