This is something that encapsulates IP (v4 right?) in something else. Would belong into linux/net/ipv4 You already have similar implementations there See f.e. ipip.c, ip_tunnel.c and lots more (try ls linux/net/ipv4/*tunnel* ) If this is more like a device then it would belong into linux/drivers/net/hfi or so (see also linux/drivers/net/ppp, plip, loopback, etc etc)
