The DHCPv6 support includes IPV6 dhcp-range and dhcp-host for one IPv6 subnetwork on one interface. This support will only work if dnsmasq version >= 2.64; otherwise an error occurs if dhcp-range or dhcp-host is specified. Note that the check for dnsmasq version is performed at network start and only then will an error condition occur. Thus, it is possible to define/edit a network configuration which will not start. The error message indicates that dnsmasq version 2.64 or later is required. This patch provides the same DHCP support for IPv6 which has been available for IPv4. With dnsmasq >= 2.64, support for the RA service is now provided by dnsmasq (radvd is no longer needed/used/started). Documentation has been updated to reflect the new support.
