uipv6: NS 16 byte NS link layer option

Dear All,

  I have been using contiki and uipv6 for some time to experiment with
ad hoc routing and clustering protocols.

I would like to make a sensor node and a linux host PC connected via
IPv6, first by emulating the node in native mode. So far so good, the
only problem is that the host PC does not understand the 16-byte link
layer option in the NS sent by uip6 so it silently drops the packet.
If I simply modify this link layer option and trim the length of the
ll address to 8 bytes, then the NS will be processed by the host PC.

My question is whether you have a preferred way or library to do this?
I use a version inherited from the avr-raven platform.

Thank you in advance,

Yours, Daniel
