I guess that it could be accepted, I guess you can easily use the netlink api for cases where the "unit" option isn't specified and fall back to the ioctl api when it is. If all goes well, then we can extend the netlink api to accept a unit id. But what about the lack of netlink feedback about the created interface? Are you restricted to use netlink only when the "ifname" option is provided? > specially if there still would be backward compatibility via ioctl for > kernels which do not support rtnl API. Indeed, I'd expect keeping compatiblitity with old kernels that only have the ioctl api to be a must (but I have no experience contributing to the pppd project). > One of the argument which can be > used why rtnl API is better, is fixing issue: atomic creating of > interface with specific name. Yes, that looks useful.
