This patch adds CPU utilization measurement and idle cycle rate computation to packet framework. The measurement is done by measuring the cycles spent while a thread pulls zero packet from RX queue. These cycles are treated as idle cycles (or headroom). A CLI command is added to display idle cycle rate of specific thread. The CLI command format is shown as following: t <thread_id> headroom Signed-off-by: Fan Zhang <roy.fan.zhang@intel.com> Acked-by: Cristian Dumitrescu <cristian.dumitrescu@intel.com>
