Changing the advertised TCP window will only help if there is only a single connection.

Yes of course. In my use case I had only one TCP connection that required a high bandwidth at any given time so I didn't really bother about that fact. But it can be a problem in other use cases.

Can I have the SGDMA collect up to 8 packets before interrupting?

IIRC if you create a chain with 8 descriptors (plus a 9th with owned_by_hw to stop the transfer) you can configure the SGDMA to generate an interrupt at the end of the chain rather than after each descriptor is processed. Of course it will require to modify the driver a bit.
