Implements UART char device driver for example. Uses following Linux facilities: module, platform driver, file operations (read/write, mmap, ioctl, blocking and nonblocking mode, polling), kfifo, completion, interrupt, tasklet, work, kthread, timer, misc device, proc fs, UART 0x3f8, HW loopback, SW loopback, ftracer.
Most of the drivers for hardware on your computer are open-source and integrated into Linux itself. These hardware drivers are generally part of the Linux kernel, although bits of graphics drivers are part of Xorg (the graphics system), and printer drivers are included with CUPS (the print system). network drivers receive packets asynchronously from the outside. Thus, while a block driver is askedto send a buffer toward the kernel, the network device asksto push incoming packets toward the kernel. The kernel interface for network drivers is designed for this different mode of operation. Linux has a monolithic kernel. For this reason, writing a device driver for Linux requires performing a combined compilation with the kernel. Another way around is to implement your driver as a kernel module, in which case you won't need to recompile the kernel to add another driver. We'll be concerned with this second option: kernel modules. With the driver model, devices are not registered in the module initialization function. Rather, the module registers a PCI driver, a platform driver, a USB driver, etc. at initialization time, and the 2 Linux network driver development Training lab book Linux network driver development Training lab book Linux Driver for the Pensando(R) Ethernet adapter family; Linux Driver for the Synopsys(R) Ethernet Controllers "stmmac" Linux and the 3Com EtherLink III Series Ethercards (driver v1.18c and higher) 3Com Vortex device driver; Linux kernel driver for Elastic Network Adapter (ENA) family; Marvell(Aquantia) AQtion Driver The Linux* igb driver supports all 82575, 82576, 82580, I350, I354, and I210/I211 based Intel® Gigabit Ethernet Network Connections. For driver configuration details, see the Read Me file in Download Center. Overview. The Linux base drivers support the 2.4.x, 2.6.x and 3.x kernels. Implements UART char device driver for example.

And writing device drivers is one of the few areas of programming for the Linux operating system that calls for unique, Linux-specific knowledge. For years now, programmers have relied on the classic Linux Device Drivers from O'Reilly to master this critical subject.
Linux Device Drivers, Third Edition This is the web site for the Third Edition of Linux Device Drivers , by Jonathan Corbet, Alessandro Rubini, and Greg Kroah-Hartman. For the moment, only the finished PDF files are available; we do intend to make an HTML version and the DocBook source available as well. The dev pseudo-file contains network device status information. This gives the number of received and sent packets, the number of errors and collisions and other basic statistics. Linux Find Wireless Wifi Driver Chipset Information; Finding Linux WiFI driver information on Linux; Network interfaces are the third standard class of Linux devices. The role of a network interface within the system is similar to that of a mounted block device. A block device registers its features in the blk_dev array and other kernel structures, and it then "transmits" and "receives" blocks Device drivers take on a special role in the Linux kernel. They are distinct programmatically abstracted "black boxes" that make a particular piece of hardware respond to a well-defined internal programming interface; they hide completely the details of how the device works.
You can also download a driver from the internet, then just double-click it to run a wizard or import the driver through Device Manager. This process isn't as easy on a Linux operating system. For one reason, Linux is an open source operating system, so there are hundreds of Linux distribution variations.

As a note, the driver development was done in C and as a module, so I assume its readers to be significantly exposed to C and l inux environment. The document intends only to show some essential points in building a driver for a network card.
