NVGRE for Linux

Hi,

Is there anyone working on implementing NVGRE [1] in Linux kernel?

A significant part of the code can be borrowed from VXLAN [2] (netlink
ops, fdb ops),
while another important part (packet reception/transmission) is based
on GRE tunneling code [3].

Is this approach correct? Any suggestions are welcomed.

thanks,
Daniel.
