Hi Thomas,
All the open issues from the former patches are closed.
Could you please have a look and get it applied ?

> It provides unit test to measure cycles/packet in NIC loopback mode.
> It simply gives the average cycles of IO used per packet without test equipment.
> When doing the test, make sure the link is UP.
>
> There's two stream control mode support, one is continues, another is burst.
> The former continues to forward the injected packets until reaching a certain
> amount of number.
> The latter one stop when all the injected packets are received.
> In burst stream, now measure two situations, with or without desc. cache conflict.
> By default, it runs in continues stream mode to measure the whole rxtx.
>
> Usage Example:
> 1. Run unit test app in interactive mode
> app/test -c f -n 4 -- -i
> 2. Set stream control mode, by default is continuous
> set_rxtx_sc [continuous|poll_before_xmit|poll_after_xmit]
> 3. If choose continuous stream, there are another two options can configure
> 3.1 choose rx/tx pair, default is vector
> set_rxtx_mode [vector|scalar|full|hybrid]
> Note: To get acurate scalar fast, plz choose 'vector' or 'hybrid' without
> INC_VEC=y in config
> 3.2 choose the area of masurement, default is rxtx
> set_rxtx_anchor [rxtx|rxonly|txonly]
> 4. Run and wait for the result
> pmd_perf_autotest
>
> For who simply just want to see how much cycles cost per packet.
> Compile DPDK, Run 'app/test', and type 'pmd_perf_autotest', that's it.
> Nothing else needs to configure.
> Using other options when you understand and what to measures more.
