Send firmware a Smart FIFO Configuration host command to allow interrupt coalescing. The smart FIFO is enabled when there is only one bound interface (other than p2p devices which are ignored) and it is of type station, and activated while the station is associated. Smart Fifo allows aggragations of DMA transactions and by that causes processor and memory controller to stay for a longer time on lower c-states, thus saving platform power. Firmware relies on driver to activate and disable it. Signed-off-by: NLilach Edelstein <lilach.edelstein@intel.com> Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com>
