> To further continue 'vport open', initialize all the resources
> required for the interrupts. To start with, initialize the
> queue vector indices with the ones received from the device
> Control Plane. Now that all the TX and RX queues are initialized,
> map the RX descriptor and buffer queues as well as TX completion
> queues to the allocated vectors. Initialize and enable the napi
> handler for the napi polling. Finally, request the IRQs for the
> interrupt vectors from the stack and setup the interrupt handler.
> 
> Once the interrupt init is done, send 'map queue vector', 'enable
> queues' and 'enable vport' virtchnl messages to the CP to complete
> the 'vport open' flow.
