If a 6Lo router sends and RA over a non-6Lo interface it should not include the options which are specifically for 6Lo ND

Contribution description
We have put a Raspberry Pi behind a 6Lo network and discovered that the 6Lo router includes the 6Lo ND options in router advertisements over the non sixlowpan interface to the Pi.
This behaviour is probably not useful/intended. So we check if the interface over which the RA is sent, is a 6Lo interface before the 6Lo ND options are appended.
Testing procedure
Our setup is Raspi --> 6LBR --> 6LR --> Raspi
