This functions is used as a converter from IPv6 address string notation to struct ip6_addr that is used everywhere in IPv6 implementation. For example it is used to parse and convert IPv6 address from tftpboot command. Conversion algorithm uses two passes, first to verify syntax and locate colons and second pass to read the address. In case of valid IPv6 address it returns 0.
Examples of valid strings: 2001:db8::0:1234:1 2001:0db8:0000:0000:0000:0000:1234:0001 ::1 ::ffff:192.168.1.1
Examples of invalid strings 2001:db8::0::0 (:: can only appear once) 2001:db8:192.168.1.1::1 (v4 part can only appear at the end) 192.168.1.1 (we don't implicity map v4)
Series-changes: 3
- Added function description
- Added length parameter to string_to_ip6()
Series-changes: 4
- Fixed function description style
