    This patch adds to the initialization flow by getting switch
    configuration, scheduler configuration and device capabilities.
    
    Switch configuration:
    On boot, an L2 switch element is created in the firmware per physical
    function. Each physical function is also mapped to a port, to which its
    switch element is connected. In other words, this switch can be visualized
    as an embedded vSwitch that can connect a physical function's virtual
    station interfaces (VSIs) to the egress/ingress port. Egress/ingress
    filters will be eventually created and applied on this switch element.
    As part of the initialization flow, the driver gets configuration data
    from this switch element and stores it.
    
    Scheduler configuration:
    The Tx scheduler is a subsystem responsible for setting and enforcing QoS.
    As part of the initialization flow, the driver queries and stores the
    default scheduler configuration for the given physical function.
    
    Device capabilities:
    As part of initialization, the driver has to determine what the device is
    capable of (ex. max queues, VSIs, etc). This information is obtained from
    the firmware and stored by the driver.
