Yes, it's self contained. There is just a new E100.c file and little enabling 
code in pci.c and Makefile.target. And it quite fits current device model 
framework.

Oh, I don't know how current QEMU's eepro100 looks like. Tristan sent an 
attachment which is original version of eepro100 implementation of QEMU one 
year ago. In the beginning, I want to fix that code to make IA64 work. After 
few days attempt, I found there are too much bugs to fix so that I gave it up 
and re-write a new one.
This version has some codes copied from the old one. Maybe we can consider it 
as offspring of QEMU's, since it has no relation with QEMU CVS version.
