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 :)
