*
* Untested:
*
* Intel 8255x 10/100 Mbps Ethernet Controller Family
* Open Source Software Developer Manual
+ *
+ * TODO:
+ * * PHY emulation should be separated from nic emulation.
+ * Most nic emulations could share the same phy code.
+ * * i82550 is untested. It is programmed like the i82559.
+ * * i82562 is untested. It is programmed like the i82559.
+ * * Power management (i82558 and later) is not implemented.
