First, let's take a look at the diagram of a major multi-queue network card (E1000) with multi-core CPUs:
Non-multiple queues:
The Linux network card is represented by the structure body Net_device, one of which corresponds to a dispatch packet sending queue.
The entity of the packet is Sk_buff (SKB) in the kernel, i
