639f7dc020 gnrc_ndp: fixed ND Option handling for 6LoWPAN 
The forms of the Source/Target Link-layer Address option for 6LoWPAN are defined
in RFC 4944 Section 8:
https://tools.ietf.org/html/rfc4944#section-8
The address is 16 bit if length is 1, 64 bit if length is 2.

64a653496a gnrc: ndp: fix calculation of L2 address length 
If no source address was provided by layer 2 or someone removed it, the calculation of its length is done using the length field from the Source/Target Link-layer Address option (https://tools.ietf.org/html/rfc4861#section-4.6.1). The length is specified as units of 8 octets. Hence, it should be multiplied by 8, not divided.

cc0101472e 6lowpan: do garbage collect unreachable NCEs 
RFC6775 says "if NUD on the router determines that the host is UNREACHABLE (based on the logic in [RFC4861]), the NCE SHOULD NOT be deleted but rather retained until the Registration Lifetime expires." Since this is a "SHOULD NOT" and not a "MUST NOT", we can still remove these NCEs to circumvent NCEs going into UNREACHABLE and never leave this state again. Actually removing these entries from the cache seems also be the better choice for memory constraint device.
