We divide a package into three phases: the network card phase, the DMA phase, and the network card drive.
The dynamic program phase (excluding the DMA part) will measure how long the Exit and Entry packets are waiting in these three phases.
The measurement method is to first determine the start point of each stage and then use rdtscll (defined in) to capture

I had to re-download a DVD image and install GCC and other development tools.
Download a copy of the kernel mode to re-compile the kernel code. The advantage of this is that the GCC version used for the compiled kernel image is naturally the same as the version used for the driver code to be compiled later,
This avoids a lot of trouble, because the GCC version required for compiling the driver is the same as the GCC version for compiling
