dhcpv6-pd: T2506: add option to request specific prefix length
Some ISPs (e.g. Comcast) only delegate a /64 by default. You have to explicitly "ask" for a bigger (e.g. /60) prefix. This commit adds a CLI node to request a specific prefix length in the range 32 - 64. dhcpv6-options { prefix-delegation { length 60 } }
