It is the skb path of Linux kernel. I would like enlarge the flow always.
Because I want to focus on the skb path from the lay 2 to socket layer, so the driver is not that I care about. I just selected the intel's e1000 driver to explain the NAPI.
There are two reasons as following
- Intel's driver is more clear than other vendor's.
- The e1000 driver is most simplest and is enough to show the NAPI
