Hi,
Specifications Sheet v3 from Librerouter says:
2 x Gigabit Ethernet RJ-45
This [1] (Preliminary version) says:
"The Ethernet switch is a highly integrated twoGb MAC plus 5-port fast
Ethernet switch with non-blocking switch fabric"
I understand this means:
5-port fast Ethernet switch
2 x Gigabit ethernet RJ-45
But I don't see this 2 gigabit ethernet in the features (first page).
Is there a definitive version of what capabilities have AR9344? PDF?
Cheers,
Pedro

According to AR9344 datasheet GMAC1 (2nd Gigabit interface in the SoC)
is hardwired to the Fast Ethernet switch. As this switch is only Fast
Ethernet capable it's creating a bottleneck.
Only GMAC0 (1st Gigabit interface) provides externally accessible RGMII
pins (Reduced Gigabit Media Independent Interface).
But I could be wrong :)

The attached screenshot from the Atheros Reference circuit shows the AR9344
supporting 5 x 10/100 Ethernet ports and the AR8327 chip supporting 5 x
10/100/1000 Ethernet ports.

According to the following document there's no separate switch chip
(like AR8327) within Librerouter. Therefore you would only have a single
Gigabit Ethernet interface.
https://librerouter.org/media/document/librerouter_specifications_v3.pdf
Although the same document mentions "2x Gigabit Ethernet RJ-45".
If I understand the AR9344 datasheet correct, the second Gigabit
interface has to go through the internal 100Mbps switch. Therefore the
OS would show 1000Mbps but in real life you are limited to 100Mbps.
Not very nice :(

Could you outline the use case for the two Gigabit ports in use?

I don't have a specific use-case. I'm just trying to help Pedro to
clarify this technical detail.
But it might be a problem that the official specifications from
Librerouter are including 2x Gigabit Ethernet. Those I assume somebody
had a use-case in mind where this is needed. Maybe something like
daisy-chaining Librerouters.

exactly :)
the idea is to be able to put two librerouters on the same pole, one
powered from the floor with a long cable, and the other one powered over
PoE passthrough via a short ethernet cable, and have a gigabit link
between them. So, you can make 4 independent p2p links from the same
"node", with full performance
the bug in the specsheet, in any case, is that ar8327 is not specified;
thanks for the pointer!

It may be worthwhile making some of the unused Ethernet ports available as
pin headers on the board.
This would allow additional linking of boards locally without requiring the
magnetics and protection components.
