[dpdk-dev] [PATCH v2] PMD for performance measurement

[mukawa at igel.co.jp]

From: Tetsuya Mukawa <mukawa at igel.co.jp>

Hi,

Here are patches to add the new PMD like '/dev/null'.
This PMD is a driver for virtual device. When an application call rx,
it just allocates mbufs and returns those. Also tx, it just frees mbufs.

Main purpose of the PMD is measuring rough throughputs of a VDEV PMD.
To measure rough throughputs between PMD1 and PMD2, prepare following
environment.

+-------------------------------+
|           testpmd1            |
+-------------+------+----------+
| Target PMD1 |      | null PMD |
+---++--------+      +----------+
    ||
    || Target path
    ||
+---++--------+      +----------+
| Target PMD2 |      | null PMD |
+-------------+------+----------+
|           testpmd2            |
+-------------------------------+

changes from v1:
* change the copyright of Makefile.
* change commit log.
* change config file not to link the PMD statically.

changes from RFC:
* change the copyright of this PMD.
* change commit logs.
