    iwlwifi: mvm: prepare for scheduler config command · 3edf8ff6
    Avri Altman authored
    The scheduler is a HW sub-block that directs the work of the Flow
    Handler by issuing requests for frame transfers, specifying source
    and destination. Its primary function is to allocate flows into the
    TX FIFOs based upon a pre-determined mapping.
    
    The driver has some responsibilities to the scheduler, namely
    initialising and maintaining the hardware registers. This is
    currently done by directly accessing them, which can cause races
    with the firmware also accessing the registers.
    
    To address this problem, change the driver to no longer directly
    access the registers but go through the firmware for this if the
    firmware has support for DQA and thus the new command.
