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.
