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.
first of all, are you using a A/B revision of the module?
Then please fetch the latest u-boot and kernel from https://git.congatec.com/ and test it again. If the problem persist write back.
