Networking from the Bottom Up: Device Drivers

In this tutorial I will describe how to write and maintain network drivers in FreeBSD and use the example of the Intel Gigabit Ethernet driver (igb) throughout the course.

Students will learn the basic data structures and APIs necessary to implement a network driver in FreeBSD. The tutorial is general enough that it can be applied to other BSDs, and likely to other embedded and UNIX like systems while being specific enough that given a device and a manual the student should be able to develop a working driver on their own. This is the first of a series of lectures on network that I am developing over the next year or so.
