If the device just connects to the Linux machine through Ethernet, then you don't need to write a kernel driver at all - a userspace daemon can have full access to Ethernet through the AF_PACKET socket address family. See the packet(7) man page for details.
In computer networking, TUN and TAP are virtual network kernel interfaces. Being network devices supported entirely in software, they differ from ordinary network devices which are backed up by hardware network adapters . The Universal TUN/TAP Driver originated in 2000 as a merger of the corresponding drivers in Solaris, Linux and BSD. Apr 26, 2006 · Linux device drivers (second edition). Ed. O’Reilly. This book is available for free on the internet. Jonathan Corbet. 2003/2004. Porting device drivers to the 2.6 kernel. This is a very valuable resource for porting drivers to the new 2.6 Linux kernel and also for learning about Linux device drivers. B. Zoller. 1998. For devices on custom boards, as typical of embedded and SoC-(system-on-chip) based hardware, Linux uses platform_data to point to board-specific structures describing devices and how they are connected to the SoC. This can include available ports, chip variants, preferred modes, default initialization, additional pin roles, and so on. Feb 14, 2005 · 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. the Linux Network Stack … plus hints on Lab 9. Some Words Passes it to the device driver. Lab 9 Scenarios, hints, etc. Lab 9 Part 1&2 Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards.
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).

Nov 19, 2012 · User-space network drivers The memory required by a network device driver can be of three types: a. Configuration space: this refers to the common configuration registers of the device. b. I/O descriptor space: this refers to the descriptors used by the device to access data from the device. c.
