+         Enable IPv6 support. It includes Neighbour Discovery protocol, ICMPv6
+         and auxiliary stuff to make it work. Since it is enabled u-boot
+         network subsystem can get and handle incoming packets and send packets
+         through IPv6 network. It allows to use environment variables such as
+         ip6addr, serverip6. If a u-boot command is capable to parse an IPv6
+         address and find it, it will force using IPv6 in the network stack.
