I just tumbled over another issue about this:
The patch suggests to create a NdiscCache only for ARP devices (which are the
only ones who really need it), but ICMPv6 assumes that there exists a cache for
every interface.

Sebastien: what would you prefer?
1. create a NdiscCache for all interfaces (including non-ARP)
   (simple, but may result in including link-layer options in ICMP messages
    where they are not needed (not allowed?))
2. modify ICMPv6 to check for non-ARP device and use the cache only if really
   needed (lots of changes in ICMPv6 required)
