Sources for tulip

[Alexander Wallace <awallace@rwsoft-online.com>]

Hello there... My laptop needs a modifyed version of tulip... I found it
in www.linuxlaptop.net its tulip_core.c

I'm supposed to copy it to /usr/src/linux/drivers/net/tulip and recompile
the module (tulip.o)

But there is nothing in the /usr/src directory since I installed from the
net, and I guess I didn't install any sources...

Coan someone tell me what I need to apt-get and then how to recompile the
module? I know that recompiling the kernel will recompile the module, but
I don't even know yet how to do that...

Thanks!
