Hi Raimund, welcome to the RIOT community! Sorry for the late reply.
For auto-configuration: Have you tried compiling with `-DGNRC_IPV6_NIB_CONF_SLAAC=1` already [1]? This compile time configuration is set to 0 for 6LoWPAN/IEEE802.15.4 nodes. 6LoWPAN nodes use a slightly different way of stateless address auto-configuration [2] from the classic SLAAC [3] which inclusion is controlled with the configuration flag. However, Linux does not really support the 6Lo-way of SLAAC so without classic SLAAC activated the address can't be validated as the ARO is missing from the NAs [4]. Am So., 25.

Were you able to pin-point the regressing commit with tools like `git bisect` or `git blame` (mentioning "git diff analysis" makes me think you roughly know which line causes the behavior)? Knowing this change would be a great help to determine what is causing this bug.
