NanoPi R6S wrong network interface naming

[Afritic Group]

Unfortunately, there seems not yet to be an area in this forum for NanoPi R6C/S, so here we go ...

 

Here is the default Armbian /etc/udev/rules.d/70-persistent-net.rules

 

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", KERNELS=="fe1c0000.ethernet", NAME:="wan"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="r8169", KERNELS=="0003:31:00.0", NAME:="lan1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="r8169", KERNELS=="0004:41:00.0", NAME:="lan2"

 

This does not match up with the labels on the case!

Here is the correct config we have updated and tested on a NanoPi R6S at Afritic Group:

 

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", KERNELS=="fe1c0000.ethernet", NAME:="lan2"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="r8169", KERNELS=="0003:31:00.0", NAME:="wan"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="r8169", KERNELS=="0004:41:00.0", NAME:="lan1"

So now with this updated config, the internal and external names match up!

Please test with both kernels, 6.12.y and stock 6.1.y and then propose changes:

Standard support forums are missing. Will be adjusted later

[Afritic Group]

Current Kernel is
Linux  6.1.75-vendor-rk35xx #1 SMP Tue Nov 12 08:48:32 UTC 2024 aarch64 GNU/Linux

Note that for the NanoPi R6C it is correct. Although lan2 could be removed because PCI-E 0004 node contains my NVME SSD.

 

EDIT: I see https://github.com/armbian/build/blob/main/config/boards/nanopi-r6c.csc

is correct, no lan2.

It is just that on my installation the rules file is not updated. It is from image older than a year.

@eselarm: Thank you for your feedback! So to double check: The labels on the hardware and with e.g. ifconfig are correctly matching for R6C?

[eselarm]

Yes I explicitly checked. I personally do not really care about the labels/names in the software, although I must know what is what. I look at the picture of the PCB mostly. Or '1G' and '2.5G' that make more sense in my case as I do not use it as a router. I have defined a software ethernet bridge br0 that includes both ports as I need that for virtualization anyway.

[Afritic Group]

@Igor: Is there really a chance that Kernel 6.12.x would address PCIe different than 6.1.x? Aren't those addresses in hardware?

[eselarm]

It is the same for all kernels, I have installed and run 6.12.2 and 6.1.84. If it would be a PC motherboard you could swap PCI-E cards physically, but this SBCs is all soldered hardware. Extra sticker/labels on the case is maybe an option. Or FriendlyElec should have just numbered them eth0 eth1 eth2. Ubiquity routers have that. Or part of MAC address.
