Isn't ipv6_add_addr called by addrconf_prefix_rcv_add_addr, which is
called by addrconf_prefix_rcv, which is called by
ndisc_router_discovery? That is what happens when we process an RA;
AFAICS manual configuration is inet6_addr_add, not ipv6_add_addr.

Maciej, with this patch, do SLAAC addresses still have RTF_ADDRCONF?
Per my previous message, my assumption would be no, but I might be
misreading the code.
