[e1000] Update e1000 driver

Browse Source 
This commit replaces the current gPXE e1000 driver with one ported
from Intel source code available at

    http://sourceforge.net/projects/e1000/

which is upstream source for the Linux kernel e1000 drivers, and
should support most if not all PCI e1000 variants.
