For PTP iface, the list contains at most one entry (so the scan is fast :-) ) and you have to examine it anyways to know neighbor's IP address.
Yes, it is a small improvement I guess and you would find the remote IP address, if there is one, by following the ifa ptr.
You cannot get remote IP address just from ifa - you can have ethernet network with (e.g.) /24 IP prefix configured as ptp iface (which is OK if there is just two routers on that network).
Oh, so "opposite" in struct ifa { .. ip_addr opposite; /* Opposite end of a point-to-point link */ does not contain an IP address in this case? Jocke
