Looks like memory is not initialised with zeroes. Will fix. Just add the following line to the start of the routine src/net/ipv6.c:inet6_aton()

    memset ( inp, 0, sizeof ( struct in6_addr ) );
 
at line around 830.

Your IPv6 network is 2001:db8::/64. What bits from IPv4(?)?

I'm currently working on net_driver to send NDP when network interface brought up. This should be sufficient to the proper auto-configuration.

Michael, would it be fine to accept multiple RAs but allow to set/edit only one manual IPv6? Other IPv6 address could be seen via "route" command. Otherwise, is there any suggestions to have multiple edit like:

net0/
 ....  ip6/
 ......... 0 -> "2001:db8::1/64 via 2001:db8::"
 ......... 1 -> "2a02:6b7:0:c32::d5/64 via 2a02:6b7:0:c32::"

and parse/format it to/from ipv6 miniroute linked list. Indexes "0", "1" might represents a reference to an item in the list.
