I haven't tried nfsroot, but I've been using USB networking for ssh
for a couple of years without issues. I have g_ether as module.

Also I recently switched rootfs to u-SD card, and it (MMC) works fine
as builtin.

But I'm mounting it from userspace (using builtin initramfs inside
zImage), with a poll loop that waits for a device to appear. Maybe if you
do it from kernel you need to use root wait/delay etc. options?
