FS#2133 - lan rx performance on IPQ806X (R7800)
Supply the following if possible:
- Device problem occurs on R7800
- Software versions of OpenWrt 18.06/Trunk
Firstly ,I found my ps4 download speed only 100mbps,so I’ve run iperf3
The lan rx work in problem ,tx works no problem.
One pair rx only 18mbps ten pair rx only 100mbps but tx can run in 1gbps.
So I change to offical 18.06.2 banch,rx is 400mbps ,tx is 1Gbps. Still in problem.
After I compile trunk banch ,it also WIP as 18.06 banch.
This problem also mentioned in FS#1598

Unfortunately, this is a hardware limitation. The R7800 has a separate CPU dedicated to speeding up network traffic. There has been some work on getting it working with OpenWrt but nothing usable yet.
One solution that several people have mentioned is to force the CPU to run at full speed.
