Hey Martine,
thanks a lot, that was what I was looking for!

Just take the current ng_icmpv6/feat/initial branch in my repo (PR'ed in
#2555) + your favorite device driver. Start your device in a nomac
thread (look into tests/driver_xbee for how to do it) and add
ng_icmpv6_echo, ng_netbase and ng_nomac to your application's modules.
Currently you have to set up your local IP addresses by hand using
ifconfig in the shell and you also have to populate the neighbor cache
with the ncache command.
That's exactly what I needed. I can now ping6 a native instance of riot
using the dev_eth+tap driver.
What I stumpled upon on the way:
- also have to populate the neighbour cache of the Linux box I used to
ping from (doh)
- our native tap drivers take the mac address from the tap interface. if
using the same tap interface on the host, the mac addresses collide. I
solved this by just incrementing the last byte of tap's mac address. As
tap mac addresses are random, that *should* be ok with 1:2^48
probability, right?
- (bug in icmpv6? [1])
It seems very reliable and quite fast:
