* ========================================================================
* 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
* instead of macros
