TX2 Linux upstream ethernet / usb firmware

Hello

I followed the manual https://elinux.org/Jetson/TX1_Upstream_Kernel for running Linux upstream on TX2 board. Unfortunately, I could not find USB/ethernet firmware for TX2 in linux-firmware git repository. So I would like to know if there is a way to use USB/ethernet on TX2 Linux upstream. Eventually does Nvidia team plan to release USB firmware?

Thanks in advance
