Just reading what I said there, I'll expand a little bit.

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.

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 !
