This article has been written for kernel newcomers interested in learning about network device drivers. It assumes that reader has a significant exposure to C and the Linux environment. This article is based on a network driver for the RealTek network card. User-mode Device Driver – Other than the devices which are brought by kernel for working of the system the user also bring some devices for use during the using of a system that devices needs device drivers to functions those drivers falls under User mode device driver. For example user needs any plug and play action that comes under this.

Like other kinds of device drivers, a network interface module connects to the rest of Linux The insane driver, for example, registers itself by calling. A network device driver is a kernel-level driver that connects a communications device to the IRIX TCP/IP protocol stack using the ifnet interface. (Putting the signal on the line is the layer-1 or the Physical layer of OSI.) Examples of MAC drivers are those for Ethernet, Fiber Distributed-Data Interface.
