+l2fwd - jobstats test plan
+== == == == == == == == == == == == == == == == ==
+
+This test plan will cover the basic l2fwd - jobstats case
+and will be worked as a regression test plan.
+
+Test Case1:
+ check different send rate the sample received rate
+== == == == == == == == == == == == == == == == == == == == == == == ==
+1. Bind two NIC port to igb_uio, then launch the l2fwd - jobstats sample
+
+ app / l2fwd - jobstats - c 0x03 - n4 - - -q 2 - p 03 - l
+ testpmd >
+
+2. Check the output, the Idle(Job) should occupy most of the CPU time
+and all statistic is zero. Like following:
+
+Port statistics == == == == == == == == == == == == == == == == == == ==
+Statistics for port 0 - -----------------------------
