From: Kai-Heng Feng kai.heng.feng@canonical.com
commit e43a12f1793ae1fe006e26fe9327a8840a92233c upstream.
KY-688 USB 3.1 Type-C Hub internally uses a Genesys Logic hub to connect to Realtek r8153.
Similar to commit ("7496cfe5431f2 usb: quirks: Add no-lpm quirk for Moshi USB to Ethernet Adapter"), no-lpm can make r8153 ethernet work.
