Thanx alot for the encouragement...
Is it possible that you give me some hints of how or where I can start?
Would this envolve with writing another Network driver? I beleive there are
good reference about this subject; which one do you recommand?
Currently in the sourse code I am studying the irq.c in Linux and the
network drivers, where else would you recommand?
Thanx alot
