If I understand the procedure correctly now, its as follows:

Any client network command on u-boot's command prompt like ping, dhcp, tftp
etc. will 'up' the USB Device...
The host to which it is connected to will happily discover and enumerate
a network adapter with MAC and IP addresses...
And the host will be the server for that command...

Best Regards,
Reinhard
