Linux kernel source tree

The ice_vsi_setup function, ice_vsi_alloc, and ice_vsi_cfg functions have grown a large number of parameters. These parameters are used to initialize a new VSI, as well as re-configure an existing VSI Any time we want to add a new parameter to this function chain, even if it will usually be unset, we have to change many call sites due to changing the function signature. A future change is going to refactor ice_vsi_alloc and ice_vsi_cfg to move the VSI configuration and initialization all into ice_vsi_cfg. Before this, refactor the VSI setup flow to use a new ice_vsi_cfg_params structure. This will contain the configuration (mainly pointers) used to initialize a VSI. Pass this from ice_vsi_setup into the related functions such as ice_vsi_alloc, ice_vsi_cfg, and ice_vsi_cfg_def. Introduce a helper, ice_vsi_to_params to convert an existing VSI to the parameters used to initialize it. This will aid in the flows where we rebuild an existing VSI. Since we also pass the ICE_VSI_FLAG_INIT to more functions which do not need (or cannot yet have) the VSI parameters, lets make this clear by renaming the function parameter to vsi_flags and using a u32 instead of a signed integer. The name vsi_flags also makes it clear that we may extend the flags in the future. This change will make it easier to refactor the setup flow in the future, and will reduce the complexity required to add a new parameter for configuration in the future.

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.
