Can it be that with the upgrade to 24.10.1 an attached usb tethering phone changed interfaces?
When I set up USB tethering under 24.10.0 the phone was registered as eth.2 interface. However after the upgrade to 24.10.1 usb tethering did not work anymore until I figured out the eth.2 interface did not exist anymore. Apparently it had changed to usb0.....
