[riot-devel] Neighborhood detection - some general questions

if you really want to use vanilla NDP (6LoWPAN-NDP assumes the
link-local IP address was automatically generated from the hardware
address) in a LoWPAN, compile gnrc_networking with the following
modules instead of `gnrc_ipv6_router_default`:

USEMODULE += gnrc_sixlowpan
USEMODULE += gnrc_sixlowpan_frag
USEMODULE += gnrc_sixlowpan_iphc
USEMODULE += gnrc_ipv6_router # (or gnrc_ipv6 for host behavior)
USEMODULE += gnrc_icmpv6
USEMODULE += gnrc_ndp_router # (or gnrc_ndp_host for host behavior)

Did not test this configuration for a while now, so this might not work at all.

Be aware however, that this also might be more power consuming, since
this causes a lot more broadcasts in your network.
