I see you as well on the RIOT mailinglist. Do you has these issues with
RIOT?

You can check it with fakelb and bsd-netcat and create/connect udp v6 socket,
if it works with a linux<->linux connection, otherwise something is
wrong with interoperability (which you can might debug via sniffing).

I know they have recently added the rfc6282 udp nhc compression, see
[0]. We have nhc_udp enabled by default, (receive handling should have
a always possible strategy).

Usually you can disable UDP NHC by unloading the "nhc_udp" module if you
built it as module. But then you can also not receive anymore other udp
nhc iphc headers.

To make a fine granularity setting to the nhc strategy, we need a
userspace tool and interface for that.
