[PATCH 1/2] Netperf: use "runs" when "confidence" is specified

[Ondrej Lichtner]

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

The "runs" module option was used to specify how many times should the
test module run the netperf client, however it was ignored when
"confidence" was specified since the user was expected to specify the
"-i" option in the task.

After this patch the "runs" parameter will be used even when
"confidence" is specified and will be used to add the "-i" parameter
to
the client command.

This patch also updates all the recipes tracked in the LNST recipe that
specified the -i parameter, to instead use the "runs" option.

[PATCH 2/2] regression_tests: add netperf multithreading support

[Ondrej Lichtner]

From: Ondrej Lichtner <olichtne(a)redhat.com&gt;

This patch extends the ENRT tests to allow for the use of the new
Netperf multithreading support. To do this I added two new aliases:
nperf_mode = default|multi
nperf_num_parallel = 2 (default value)

The nperf_mode alias chooses if Netperf is supposed to run in
multithreading mode or in single thread mode. Multithreading is only
enabled if the value "multi" is supplied, otherwise the default mode is
used. Enabling multithreading will automatically disable any Netperf
confidence settings supplied as these don't make sense when running
multiple netperf clients.

the nperf_num_parallel parameter changes how many Netperf clients should
be run in parallel.
