Re: nd6_na_input: duplicate IP6 address

Looking at the -8 kernel code, it will print this message before deciding on a course of action.

As it's not impacted v6 connectivity - and you can verify by ifconfig that no address is duplicated, then the kernel is notifying another node that it's address is the dupliate and not yours.

The other machine won't see this because it's using a different address.

We should probably fix the kernel messages to at least print the lla of the other node to help debugging.

So this seems to suggest that the machine thinks there is another host on the same network that has the same IP?

If so that's very odd because almost all of my machines are using auto assigned addresses based on MAC address and the ones with static addresses haven't moved for ages.
