As the mailbox is setup, add the necessary send and receive mailbox message framework to support the virtchnl communication between the driver and device Control Plane (CP). Add the core initialization. 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 etc. Based on the vector information received in 'VIRTCHNL2_OP_GET_CAPS', request the stack to allocate the required vectors. Finally add the interrupt handling mechanism for the mailbox queue and enable the interrupt. Note: Checkpatch issues a warning about IDPF_FOREACH_VPORT_VC_STATE and IDPF_GEN_STRING being complex macros and should be enclosed in parentheses but it's not the case. They are never used as a statement and instead only used to define the enum and array.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
