[ndisc6] Bad NIC causing IPV6 NDP to stop working

Hi,

We have witnessed several cases where we suspect that a bad NIC on the machine caused neighbour discovery to stop working on all the other NICs - when this happens ping6 fails on every NIC we try it.

From looking into the code I see that there is only a single socket assigned for NDP; Does it sound logical to allocate a socket per interface instead of a single global socket.

Thanks,
Menny
