I tried to use USB tethering on my OP6: not working at all (interface stays in MTP mode).
I found that RNDIS mode was just not implemented in /usr/share/usbinit/setupusb... snif...
So I modified (with success) /usr/share/usbinit/setupusb:
#!/bin/sh
CONFIG_FS=/sys/kernel/config
CONFIG_DIR=$CONFIG_FS/usb_gadget/
GADGET_DIR=$CONFIG_DIR/g1
CONFIG_NAME="c.1"
SERIALNUMBER=`getprop ro.serialno` # e.g. "0123456789ABCDEF"
MANUFACTURER=`getprop ro.product.vendor.manufacturer` # e.g. "Volla"
PRODUCT=`getprop ro.product.vendor.model` # e.g. "Phone"
CONTROLLER=`getprop sys.usb.controller` # e.g. "musb-hdrc"
write() {
test -w "$1" || return
printf "$2" > "$1"
}
symlink() {
ln -s "$1" "$2"
}

RNDIS is now fully usable with /usr/bin/tethering enable/disable and with UT Tweak Tool.
Enjoy!
