What is it you're looking for exactly? Are you trying to understand how to write the avalon master? It's pretty simple. You just follow the rules indicated in the specifications document:

I have several designs which do what you are indicating but I'm afraid they are proprietary. I can answer any questions you have.

If you like, you could take a look at the Avalon OpenCores 10/100 Ethernet MAC available in the shared material section of the forum. It has two avalon masters (DMA controllers). They are simple masters (no bursting) and only 32-bits wide.
