For example, I have a firewall with dual core CPU, and use core 0 for
IRQ and dispatching. If I use both core 0 and core 1 for the left
processing, core 0 will be overloaded, and if I use core 1 for the
left processing, core 0 will be light load. In order to take full of
advantage of hardware, I need weighted the packet distribution.
