The Radxa Rock-5B board uses an external network controller, a RealTek 8125B 2.5 Gbps controller, which is connected to the RK3588 SoC via PCI Express. And now, the networking on the board works at 100 Mbps, which is very good progress, even if the gigabit does not work yet. Publishing code as Open Source can benefit many different other projects, such as getting boards and devices up to speed, and allows anyone to benefit.
