The functions are provided as a generic stub and a x86 specific implementation. The reason to implement these functions is to improve performance by reducing the overhead associated with regular mmio writes when updating the hardware queue tails and doorbells. With this patch set the I40E, IXGBE and QAT PMDs are updated to use the write combining store functions with other PMDs to follow.
