The files are shell style syntax, and examples are in the tests provided here. There is no good documentation on this unfortunately. DEVICE=<name> is expected/required and PROTO should indicate if this is 'none' (static) or 'dhcp' or 'dhcp6' (LP: #1621507) or 'static' or 'off' (LP: 2065787). Note that IPV6PROTO is also written to address the possibility of both ipv4 and ipv6 getting addresses.
