yeah, Driver -> USB -> Gadget -> Ethernet Gadget Drive is already enabled.
In fact, I could able to use Ethernet over USB.
I am using 220.127.116.11 kernel patched with the usb_mode_swith.patch
I cross verified whether the patch is applied correctly using the tool
"nm", it listed both show_usb_mode and set_usb_mode on the ohci_hcd.ko.
Thanks n Regards,
