- * ========================================================================
- * 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
- * ========================================================================
