Implement and Porting Ethernet Drivers for gPXE

by Guo-Fu Tseng for Etherboot Project

In order to have better performance on JMicron Ethernet Card. Instead of using the UNDI driver, I would implement a better performance native driver for gPXE. The tg3 driver of gPXE project still using old etherboot API, I would buy a Broadcom NIC and try to port it into new gPXE API.
