@dsl: My ADC avalon slave is a PIO component. The PIO source code is generated, so I don't want to hack around in that. Is there a better component I can use for the ADC samples comming in?

I would really like to keep this simple, creating my own ethernet pakets is a bit to deep for me...

Don't know if you're familiar with SGDMA. I've thought of using the SGDMA's in my system. But if I want to construct a descriptor with the API functions I can only read from a memory. The "Stream-To-Memory" configuration needs an Avalon-ST source - argh! Why is this so hard finding components for this purpose!? Maybe Nios is not normaly used for ADC-Systems... but I've seen many poeple use the PIO for thier ADC's.
