This USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip used to
work with the cdc_ether driver. However, using this driver, with the
system suspended the device sends pause-frames as soon as the receive
buffer fills up. This produced substantial network load, up to the
point where some Ethern
