[U-Boot] net: re-enumerating usb-ethernet devices hangs the system

[Wolfgang Grandegger]

Hi Vincent,

as you already know, the re-enumerating of usb ethernet devices (calling
"usb start" twice) hangs the system because eth_register() is called
more than once. If have found a related patch from you with the subject
"eth: remove usb-ethernet devices before re-enumerating them" in the
chromium.org git repos. Could that be pushed mainline. Feel free to add
my "Tested-by: Wolfgang Grandegger <wg at denx.de>".

Thanks,

Wolfgang.
