This adds support for using USB Ethernet dongles in host mode. This is just the framework - drivers will come later. A new config option called CONFIG_USB_HOST_ETHER can be defined in board config files to switch this on. The was originally written by NVIDIA and was cleaned up for release by the Chromium authors.
