Power Management
================
-The Intel® DPDK Power Management feature allows users space applications to save power
+The DPDK Power Management feature allows users space applications to save power
by dynamically adjusting CPU frequency or entering into different C-States.
* Adjusting the CPU frequency dynamically according to the utilization of RX queue.
* scaling_setspeed
-In the Intel® DPDK, scaling_governor is configured in user space.
+In the DPDK, scaling_governor is configured in user space.
Then, a user space application can prompt the kernel by writing scaling_setspeed to adjust the CPU frequency
according to the strategies defined by the user space application.

Core state can be altered by speculative sleeps whenever the specified lcore has nothing to do.
