No, I'd like to have a user-space application using a plain tcp socket
as the endpoint.

In my experience, pktgen is useful if you want to test the limits of ra=
w
packet performance of network cards and drivers, or generate load on
networking equipment. But not for generating load on a real application=
,
where the data needs to follow some higher level protocol.
