The SMSC95XX is a USB hub with a built-in Ethernet adapter. This adds support for this, using the USB host network framework. The framework is extended to support setting the hardware MAC address via an environment variable, since SMSC95XX chips often have no EEPROM attached, and thus no MAC address. Documentation is added on USB networking, the auto load code is refactored to remove duplication, and the ASIX USB ethernet driver is optimized to reduce the time between successive network operations.
Changes for v2: - Coding style cleanup - Changed some comments as suggested - eth_set_hwaddr -> eth_write_hwaddr - tided up other users of eth_getenv_enetaddr_by_index()
Changes for v3: - Drop tfpserverip patch - Change turbo_mode to #define - Fix tfpserverip patch bleed
Changes for v4: - Dropped Tegra2 specific bit - Added patch in place of tftpserverip patch, to speed up successive network commands on asix - Fixed a few broken bits in SMSC from my testing
Changes for v5: - Code style clean-ups in SMSC - Cleaned up debugging of errors in SMSC driver - Changed NULL to "eth" in eth_getenv_enetaddr_by_index() API
Changes for v6: - Adjust documentation file according to Wolfgang's comments - Set NET_IP_ALIGN to 0 always
Changes for v7: - Added change logs to each patch as requested by Wolfgang
Simon Glass (5): Add support for SMSC95XX USB 2.0 10/100MBit Ethernet Adapter Add Ethernet hardware MAC address framework to usbnet Add documentation for USB Host Networking Put common autoload code into auto_load() function usbeth: asix: Do a fast init if link already established
