To enable USB Host Ethernet in U-Boot, your platform must of course
support USB with CONFIG_CMD_USB enabled and working. You will need to
add some config settings to your board header file:
add some config settings to your board config:
#define CONFIG_CMD_USB /* the 'usb' interactive command */
#define CONFIG_USB_HOST_ETHER /* Enable USB Ethernet adapters */
CONFIG_CMD_USB=y /* the 'usb' interactive command */
CONFIG_USB_HOST_ETHER=y /* Enable USB Ethernet adapters */
and one or more of the following for individual adapter hardware:
#define CONFIG_USB_ETHER_ASIX
#define CONFIG_USB_ETHER_MCS7830
#define CONFIG_USB_ETHER_SMSC95XX
CONFIG_USB_ETHER_ASIX=y
CONFIG_USB_ETHER_ASIX88179=y
CONFIG_USB_ETHER_LAN75XX=y
CONFIG_USB_ETHER_LAN78XX=y
CONFIG_USB_ETHER_MCS7830=y
CONFIG_USB_ETHER_RTL8152=y
CONFIG_USB_ETHER_SMSC95XX=y
As with built-in networking, you will also want to enable some network
commands, for example:
#define CONFIG_CMD_NET
#define CONFIG_CMD_PING
#define CONFIG_CMD_DHCP
CONFIG_CMD_NET=y
CONFIG_CMD_PING=y
CONFIG_CMD_DHCP=y
and some bootp options, which tell your board to obtain its subnet,
gateway IP, host name and boot path from the bootp/dhcp server. These
