Description (partial)

Boxer has DPI and Gx  configuration , Initially started sending 20Gbps traffic and then gradually increased  till 80Gbps throughput, the system CPU usage was ~48% and 48% CPU usage was shown on call cards CPUs (CPU0, CPU1 and CPU2). 
If traffic is increased further throughput then CPU usage of same card shows different value for same packet processing. This results in seeing uneven CPU usage at same card..
