Hi Mirek, We are not currently testing the LL TEMAC driver with the LL FIFO. We only test with the DMA configuration. I also realize this may not be documented that well and we may need to work on that.
Our reasoning is that in the Virtex5 FXT devices the DMA is hard so that it does not cost any more LUTs to use the DMA and most people want the performance. Is there a specific reason you're wanting to use the LL FIFO rather than DMA as this information might help us in the future? We would welcome any patches to the driver if LL FIFO is a needed feature.
