This series adds IPv6 network discovery to U-Boot. When an IPv6 command is run in U-Boot, it sends a router solicitation (RS) message to the network. The router on the network responds with a router advertisement (RA) message. Then U-Boot processes the RA message and sets the gatewayip6 and net_prefix_length environment variables. It is based on RFC 4861, but not everything in the RFC is supported here. https://www.rfc-editor.org/rfc/rfc4861
Changes in v2: - Improved IPv6 network discovery code. - Added IPv6 network discovery feature test (Python test). - Added unit tests (C code).
