I would like to know if you are a hardware developer because you may want to try to discuss this issue to our developer team.
I'm a board design engineer at a company where we are designing FPGA based PCIe cards which depend on payloads specified by PCIe 3.0 standards (256 bytes) to achieve a certain bandwidth. But we find that the real max payload supported by my X99 motherboard is 64 bytes.
I would like to know if this is a limitation of the Intel chipset and will it change in the next generation?
