Implement actions on ip6addr, gatewayip6, serverip6 varaibles. on_ip6addr - convert IPv6 string addr to struct ip6_addr on_gatewayip6 - convert IPv6 string addr to struct ip6_addr on_serverip6 - convert IPv6 string addr to struct ip6_addr Series-changes: 3 - Removed memory allocation - Substituted -1 for error code Signed-off-by: Viacheslav Mitrofanov <v.v.mitrofanov@yadro.com> Reviewed-by: Ramon Fried <rfried.dev@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
