Happy to help. In this assembly, there is a very interesting situation with the order and names of network interfaces, please note that in this assembly, the kernel parameter net.ifnames=0 is applied during boot, original names eth0 is enp1s0, eth1 is enP1p1s0.

@Dysmas this possible, add udev rule with name for example SUBSYSTEM=="net", ACTION=="add", DRIVERS=="rk_gmac-dwmac", KERNEL=="eth2", NAME="wan0" drivers list are eth0 : r8169 eth1 : r8169 eth2 : rk_gmac-dwmac

Cornelius, thanks! #4 succeeded only 50%, needs to be tweaked in the kernel NET_SCH_FQ_CODEL and NET_SCH_FQ options... root@r5s:~# uname -a Linux r5s 5.19.11 #4 SMP Mon Sep 26 17:57:58 EDT 2022 aarch64 GNU/Linux root@r5s:~# sysctl net.core.default_qdisc=fq sysctl: setting key "net.core.default_qdisc": No such file or directory root@r5s:~# sysctl net.ipv4.tcp_congestion_control=bbr net.ipv4.tcp_congestion_control = bbr Found problem with creating a bonding interface: root@r5s:~# modprobe bonding modprobe: FATAL: Module bonding not found in directory /lib/modules/5.19.11

Found that BBR congestion control (TCP_CONG_BBR) is not enabled in kernel (Linux r5s 5.19.11 #3 SMP Mon Sep 26 11:14:54 EDT 2022 aarch64 GNU/Linux), it is possible to enable this feature. root@r5s:~# sysctl net.core.default_qdisc=fq sysctl: setting key "net.core.default_qdisc": No such file or directory root@r5s:~# sysctl net.ipv4.tcp_congestion_control=bbr sysctl: setting key "net.ipv4.tcp_congestion_control": No such file or directory

Maybe it will help with leds if add such a file, for example /etc/udev/rules.d/nanopi-r5s-led.rules: SUBSYSTEM=="leds", KERNEL=="green:wan", ACTION=="add", ATTR{trigger}="netdev", ATTR{device_name}="eth2", ATTR{link}="1" ATTR{rx}="1" ATTR{tx}="1" SUBSYSTEM=="leds", KERNEL=="green:lan1", ACTION=="add", ATTR{trigger}="netdev", ATTR{device_name}="eth0", ATTR{link}="1" ATTR{rx}="1" ATTR{tx}="1" SUBSYSTEM=="leds", KERNEL=="green:lan2", ACTION=="add", ATTR{trigger}="netdev", ATTR{device_name}="eth1", ATTR{link}="1" ATTR{rx}="1" ATTR{tx}="1"

This should work: # cat /proc/device-tree/serial-number
