Write combining is an optimization feature in CPUs that is frequently
used by modern devices to generate 32 or 64 byte TLPs at the PCIe level.
These large TLPs allow certain optimizations in the driver to HW
communication that improve performance. As WC is unpredictable and
optional the HW designs all tolerate cases where combining doesn't
happen and simply experience a performance degradation.
