Thierry, I know that you are using DWMAC CORE 4.XX
How many RX queues and how many TX queues have you got?

I'm also using DWMAC CORE 4.XX
We have 2 TX queues and 1 RX queue.

I think that Corentin is using DWMAC CORE 3.XX

I know that Joao is using an IP Prototyping Kit that uses
DWMAC CORE 4.XX (connected via PCIe).
It would be nice if Joao could get an IP Prototyping Kit
based on DWMAC CORE 3.XX.

Doesn't Synopsys have an IP Prototyping Kit based on
DWMAC CORE 3.XX laying around somewhere? :)
