Could you outline the use case for the two Gigabit ports in use?
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_specifica tions_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 :(

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.

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 :)
