+ * gPXE driver for Marvell Yukon 2 chipset. Derived from Linux sky2 driver
+ * (v1.22), which was based on earlier sk98lin and skge drivers.
+ *
+ * This driver intentionally does not support all the features
+ * of the original driver such as link fail-over and link management because
+ * those should be done at higher levels.
