If the H2C Stream Engine encounters an error coming from PCIe on the data, it keeps the error sticky across the full packet. The error is indicated to the user on the err bit on the H2C Stream Data Output. Once the H2C Stream sends out the last beat of a packet that saw a PCIe data error, it also sends a Writeback to the Software to inform it about the error.
