[U-Boot] CONFIG_DM_ETH USB_ETHER_ASIX Reception Issue on Tegra

[Marcel Ziswiler]

Hi there

Trying to update one of my patch sets of late made me notice that the
ASIX USB to Ethernet stuff if CONFIG_DM_ETH is enabled seems to be
rather broken. I already sent two patches to even get that far but even
with that reception still does not seem to work (see below). I tested
by enabling CONFIG_DM_ETH on Colibri T20/T30 as well as Apalis T30 with
CONFIG_USB_HOST_ETHER and CONFIG_USB_ETHER_ASIX enabled and a LevelOne
USB-0301 ASIX AX88772 dongle. Has anybody actually tried that lately?
