RE: inet address mib issue

[Bill Fenner <fenner@research.att.com>]

I'm not sure it's worth it for an integer.  The InetAddress TC at least
has different lengths and DISPLAY-HINTs for different families; the prefix
would only have a different range.

   InetAddressPrefix ::= TEXTUAL-CONVENTION
       STATUS       current
       DESCRIPTION
           "Denotes a prefix length of a generic Internet address.
            Directly follows the InetAddress for which it describes
            the prefix? ..."

       SYNTAX      Integer32

   InetAddressIPv4 ::= TEXTUAL-CONVENTION
       DISPLAY-HINT "d"
       STATUS       current
       DESCRIPTION
           "Represents an IPv4 prefix length.

            The corresponding InetAddressType value is ipv4(1)."
       SYNTAX       Integer32 (0..32)

   InetAddressIPv6 ::= TEXTUAL-CONVENTION
       DISPLAY-HINT "d"
       STATUS       current
       DESCRIPTION
           "Represents an IPv6 prefix length.

            The corresponding InetAddressType value is ipv6(2)."
       SYNTAX       Integer32 (0..128)
