cdc_ether|r8152: ThinkPad Hybrid USB-C/A Dock quirk
Lenovo ThinkPad Hybrid USB-C with USB-A Dock (17ef:a359) is affected by
the same problem as the Lenovo Powered USB-C Travel Hub (17ef:721e):
Both are based on the Realtek RTL8153B chip used to use the cdc_ether
driver. However, using this driver, with the system suspended the device
constantly sends pause-frames as soon as the receive buffer fills up.
This causes issues with other devices, where some Ethernet switches stop
forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.
