Linux/TSU6721: Does the USB-OTG of tsu6721 support 100M ethernet?

Part Number: TSU6721

Tool/software: Linux

As title:

Does the USB-OTG of tsu6721 support ethernet?
Using this module, we can recognize the mouse, SD card, U disk and other devices after switching to the OTG function. But it happened when we made usb to Ethernet.
E usb1-port1: disabled by hub (EMI?), re-enabling...
Now we are stuck here to determine if we can use the chip to switch to the OTG state and then switch to Ethernet.

    Thank you, find the reason. The linux driver needs to add the USB-HOST service, which is to add CONFIG_USB_NET_RNDIS_HOST to the configuration to solve this problem.
    The legacy issue is that if you don't use the TSU6721 chip, you can use USB to Ethernet without adding this service.
