Since you want to TFTP over the USB, from your point of view, there is no reason not to use CDC_ACM/g_serial and just do a kermit binary transfer and save yourself the effort of doing Ethernet over the USB.
All you'd really have to do is implement usbdcore_au1100 and just do a straight forward kermit binary transfer .. with the 8xx and both CDC_ACM and g_serial, it works well enough for me.
Let me explain better my situation. My board have a serial line and an USBdev as I/O interfaces. In linux I'm going to use the serial line for the console and the USBdev for rootfs and other network activities. I'd like to do the same into u-boot in order to have a serial console and a TFTP file transfer.
Do you think that I can use the current implemented software (apart the usbdcore_au1100) for my purposes?
Still if you are going to do some of the ethernet side ... it would be a good excuse for me, to stay out of the pub !
