The designated method for allocating the IPv6 address via the PDP EUA (End User Address) Information Element in the GTP signalling plane is *not* used to allocate the address/prefix. Instead, the EUA is used to allocate an "interface identifier" to the MS, which it the uses to derive its link-local source address to send a router solicitation. The GGSN subsequently answers witha router advertisement, advertising a single/64 prefix, whihcthe MS then uses to generate it's real IPv6 source address for subsequent communication.

The standard prefix lengh is 8 bytes, i.e. a /64 prefix. This patch extends the pool to be able to work with such v6 prefixes.
