Congatec QMX6 Ethernet limitation ~100Mb/s

Hi,

I'm working on a Congatec QMX6, and I have an issue with Ethernet speed using the BSP provided with a kernel 3.0.35.

It tops under 100Mb/s using Iperf.

Can anybody confirm that ?

An older version with a kernel 3.0.15 which I received on a µSD didn't have this limitation and I could reach 456Mb/s which is close enough to the 470Mb/s limitation (ERRATA ERR004512).

I couldn't regenerate that version yet.

So if somebody has a clue on what might be the cause of this poor result.

Thx
