+
+    This davicom etherboot driver supports DM9009/DM9102/DM9102A/

+
+  12 OCT 2000  Sten     0.90
+			This driver was ported from tulip driver and it

+			Changed symbol tulip/TULIP to davicom/DAVICOM
+			Deleted some code that did not use in this driver.
+			Used chain-strcture to replace ring structure

+			Allocated two tx descriptor.
+			According current media mode to set operating
