> As the mailbox is setup, initialize the core. This makes use of the send and

> driver and device Control Plane (CP).

> To start with, driver confirms the virtchnl version with the CP. Once that is
> done, it requests and gets the required capabilities and resources needed such
> as max vectors, queues, vports etc.
> 
> Use a unified way of handling the virtchnl messages, where a single function
> handles all related memory management and the caller only provides the
> callbacks to fill the send buffer and to handle the response.
> 
> Place generic control queue message handling separately to facilitate the
> addition of protocols other than virtchannel in the future.
