Hi..

My descriptor chain size is 1, and callback is called when chain is completed. I am using Altera Sgdma drivers and I have tried but couldn't get the most of sgdma. In every call back I am getting a single frame from received in TSE. I have cleaned all the logic from the callback function & no malloc or memcpy is done and also using pre allocated buffer. So now what should I do to get the higher throughput. With current config i am getting my data transferred at upto 270KBPS but I need this to MBPS.
