Delegated-IPv6-Prefix(123) is shown incorrect as
X-Ascend-Call-Attempt-Limit(123). For example:

Radius Protocol
    Code: Accounting-Request (4)
    Packet identifier: 0x68 (104)
    Length: 685
    Authenticator: 18e2ca4a4ff9f9f5252ffaea4acc5def
    [The response to this request is in frame 18]
    Attribute Value Pairs
        ...
        AVP: l=20  t=Framed-IPv6-Prefix(97): 2003:4:f007:13e4::/64
            [Length: 18]
            Framed-IPv6-Prefix: 004020030004f00713e40000000000000000
        AVP: l=20  t=X-Ascend-Call-Attempt-Limit(123): [unhandled integer
length(18)]
            [Length: 18]

Such an issue could be easily solved on Radius server through a proper entry in
the radius dictionary. It is unclear, how to tell Wireshark to display the
radius attribute 123 available in Radius requests not as
X-Ascend-Call-Attempt-Limit(123) but as Delegated-IPv6-Prefix(123).

The IPv6 attribute 97 is still shown correct as Framed-IPv6-Prefix(97), but the
IPv6 attribute 123 is shown incorrect as X-Ascend-Call-Attempt-Limit.
