Research direction
Start by reproducing the reported iperf3 server/client test on the Banana Pi BPI-R4 running OpenWrt 25.12.0-rc5 for mediatek/filogic, then compare the fiber-link throughput with the expected 10 Gbps. No source files or tests are identified, so completion would require isolating the networking cause and documenting a verified improvement.
