Orange Pi 3-lts Ethernet-to-USB3.0

[sakesm]

Under kernel 4.9, using a usb3.0 to Gigabit interface with RTL8153b card, the upstream and downstream speed can reach Gigabit.
But with kernel5.10, the speed can't reach gigabit, and the driver file has been changed to the latest version, but still no effect.

Attempt to use a hub to plug into USB 3.0, and then plug the RTL8153b USB to Gigabit Ethernet port into the hub, but unexpectedly discover that the speed can reach Gigabit.
