tse (Triple speed ethernet) and SGDMA (Scatter Gather DMA) do not seem fully connecte

So I've searched, and nothing seems to quite fit my case. I am using SGDMA and TSE with InterNiche Portable TCp/IP v3.1 and Simple Socket Server demo and Altera 10.0 (or very close, maybe 10.1)...

Ok, so after spending half an hour carefully composing my reply to myself and Daixiwen, the web page nicely says 'your token has expired, press the back button and try again after reloading' (not exact, but close)... And, of course, ALL that I had written is GONE! Bah, humbug!

So, here is try two, but it will be shorter (but hopefully not much grumpier) than the one the forum decided nobody wanted to see.

After much quality time with GDB, I think that the problem is a lack of connection between the SGDMA and the TSE stream. From what I can tell, SGDMA is set to use stream 0. I bet that's wrong.

So my current theory is that I need to get the "core's streaming port" connected from the SGDMA to the TSE. How is that tie-in done?

Thanks! (Sorry for the shortness of this and the lack of as much detail as before. If more info would help, or I'm asking it wrong, please poke me (gently) in the right direction and I'll work on doing better).
