AFAICT, it's all due to the new "address FIFO". But that FIFO seems to be setup to be unreasonably large. I mean it can store as many addresses as data words ... while AFAICT it only has to store one address per packet in the buffer, so reducing it to say 32 entries should be enough. This way 6 bits can fit in 1 CLB using 32x2 distrams instead of using block rams.
