Looking at the driver (and the Linux kernel driver and SMSC's website),
it supports both the standalone USB->Ethernet 9500 chip that's likely to
be in USB Ethernet dongles, and various combo USB hub + Ethernet chips
that are found on motherboards (e.g. Harmony). As such, I think it's
reasonable to leave this config option enabled on Paz00 and other Tegra
boards even when such a chip isn't on the board itself. Do you agree?
