Re: device driver

Read this article by Alan Cox on network buffers and memory management.
It talks of some basics of device drivers.


In general u might want to implement atleast the ioctl, open and close
operations in the file_structure.

A good place to start loooking at sample code is drivers/net/skeleton.c

ps. and yes as someone pointed out, Rubini's book is good for basics
