+ * ASIX AX88180 Non-PCI 16/32-bit Gigabit Ethernet Linux Driver
+ *
+ * The AX88180 Ethernet controller is a high performance and highly
+ * integrated local CPU bus Ethernet controller with embedded 40K bytes
+ * SRAM and supports both 16-bit and 32-bit SRAM-Like interfaces for any
+ * embedded systems.
+ * The AX88180 is a single chip 10/100/1000Mbps Gigabit Ethernet
+ * controller that supports both MII and RGMII interfaces and is
+ * compliant to IEEE 802.3, IEEE 802.3u and IEEE 802.3z standards.
+ *
+ * Please visit ASIX's web site (http://www.asix.com.tw) for more
+ * details.
+ *
+ * Module Name	: ax88180.c
+ * Date		: 2008-07-07
+ * History
+ * 09/06/2006	: New release for AX88180 US2 chip.
+ * 07/07/2008	: Fix up the coding style and using inline functions
