1)as RFC4862 section 5.5 statement: Creation of global addresses as described
in this section SHOULD be locally configurable. However, the processing
described below MUST be enabled by default. 2) In other TCP/IP protocol stack,
such as Linux and FreeBSD, the IPv6 autoconfig is enabled by default. so I
suggest that IPv6 autoconfig should be enabled by default in lwip by setting
netif->ip6_autoconfig_enabled to 1 in netif_add, pls refer the attached patch.
