NETPERF

Description

Network performance benchmark server.
For those options taking two parameters, at least one must be specified; specifying one value without a comma will set both parameters to that value, specifying a value with a leading comma will just set the second parameter, a value with a trailing comma will just set the first.
To set each parameter to unique values, specify both and separate them with a comma.
* For these options taking two parameters, specifying one value with no comma will only set the first parameter and will leave the second at the default value.
To set the second value it must be preceded with a comma or be a comma-separated pair.
This is to retain previous netperf behaviour.
