[netperf-talk] Running Netperf using IPv6

[Ashenafi D]

Thank you Rick for your input.
Here is what I found from Qt:
QHostAddress isn't enough to hold proper addresses, meaning IPv6 addresses
require more information than a simple 128-bit
address. Link-local addresses in stream connections require the
sin6_scope_id field of sockaddr_in6 to be set when connect call is used,

In some Linux distros, when using a link-local or site-local address for
IPv6 connections, you must specify the scope ID. The scope ID for a
link-local address is usually the same as the interface name (e.g., "eth0",
"en1") or number ( e.g., "1", "2").
