it learns IP address of peer which encapsulated given packet.

This feature is already present in the Linux kernel, albeit only for IP
to IP lookup. Please look at "userspace ARPd" and its relation to
multipoint GRE. OpenNHRP is the associated userspace part.

That code reuses the existing neighbor management infrastructure. Adding
support for gretap and automatic learning from incoming packets
shouldn't be too hard...
