The recently integrated IPv6 patch series relies on the link-local address, or a statically assigned IPv6 address for network operations. This patch series adds IPv6 address assignment through DHCPv6.
The implementation meets the requirements in RFC 8415 for "Client/Server Exchanges Involving Four Messages": https://www.rfc-editor.org/rfc/rfc8415
The implementation sends/receives the minimum required DHCPv6 options to network boot.
A new command (dhcp6) will execute the protocol. In addition, IPv6 functionality has been extended to the existing pxe commands ("pxe get" and "pxe boot").
