> 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 functions'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.
