IPV6_V6ONLY / ??? : does the tcpConnectionTable need something?
 (Erik said:

But for the different types of wildcard listeners it would make sense
to be able to capture the difference between:
        IPv4-only - bound to INADDR_ANY
        IPv6-only - bound to in6addr_any with the IPV6_V6ONLY socket
                    option set
        both - bound to in6addr_any and the above not set

[the last 2 could probably be differentiated by the remote address AF
being Unknown or IPv6 -- which would require changing the DESCRIPTION]
