It looks like the readme file is a bit old! But as long as the example uses the Nichestack TFCP/IP stack it doesn't really matter what ethernet MAC is used. You just need a driver for the NicheStack, and the TSE has one.

From your SOPC screenshot I see that the descriptor read/write masters are going down. Are you using a special memory for the descriptors? In that case IIRC you need to indicate it by using the TSE_SYSTEM_EXT_MEM_NO_SHARED_FIFO variant (and not the INT_MEM), check that the name for the descriptors memory component is correct, and that both the SGDMAs and the Nios data master are connected to that memory.

Another alternative is to use the TSE_SYSTEM_INT_MEM_NO_SHARED_FIFO variant and connect all the SGDMA descriptor masters to the main RAM instead of a dedicated component.

If this doesn't help then you really need to see what is going on with SignalTap.
