[okl4-developer] DMA/Ethernet drivers for OKL4

Hi all,

currently I wonder, whether there are network drivers for L4/Iguana out
there, running without Wombat. 
Actually, I don't need it, but I need to know, how the drivers for DMA
capable devices look like. Is there a standalone DMA driver, stacked
with a chipset driver, an ethernet driver, IP stack, TCP stack? Or
should the DMA setup and control take place in the ethernet driver
itself? How are DMA interrupt routed to the particular driver than?

Maybe, I got something completely wrong, but I coudln't find a general
abstraction layer for DMA hardware in L4/Iguana without Wombat.

Thanks for your advice!

Martin
