+Power managerment throughput test plan
+======================================
+
+This test plan test cpu frequence changed according io workloads with l3fwd-power sample.
+The cpu frequency status depends on NIC and CPU type.
+
+Prerequisites
+=============
+
+1. Update Grub::
+
+ Add "intel_pstate=disable" in kernel options.
+
+2. BIOS configuration as below::
+
+ CPU mode : "Power"
+ Workload configuratuionï¼"IO sensitive"
+ Hardware Power : "Disabled"
+ Speedstep : "Enabled"
+ Turbo : "Enabled"
+ C-statsï¼C0/C1
+ C6 : "Enabled"
+
+Test Case1: Check the CPU frequency can change according differernt packet speed
+================================================================================
+
+1. Check that you are using the "acpi-cpufreq" driver by command "cpufreq-info".
+
+2. CPU frequency controlled by userspace by command "cpupower frequency-set -g userspace".
+
+3. Bind one nic port to igb_uio, launch l3fwd-power sample, one core used for one port::
+
+ ./l3fwd-power -c 0xc000000 -n 4 -- -P -p 0x01 --config '(0,0,27)'
+
+4. Send packets by packet generator with high speed, check the used cpu frequency is almost 100%::
+
+ cat /sys/devices/system/cpu/cpu27/cpufreq/cpuinfo_cur_freq
+
+5. Send packets by packet generator with low speed, the CPU frequency will reduce about 50%::
+
+ cat /sys/devices/system/cpu/cpu27/cpufreq/cpuinfo_cur_freq
