> Subject: [Intel-wired-lan] [PATCH iwl-next v6 13/14] ixd: add the core
> initialization
>
> As the mailbox is setup, initialize the core. This makes use of the
> send and receive mailbox message framework for virtchnl communication
> between the 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.
