Jacob Keller says:

The ice_sriov.c file now houses almost all of the virtualization code in the
ice driver. This includes both Single Root specific implementation as well
as generic functionality such as the virtchnl interface.

We are planning to implement support for Scalable IOV in the ice driver in
the future. This implementation will want to use the generic functionality
in ice_sriov.c

Rather than dump the Scalable IOV code into ice_sriov.c, we will want to
implement it in a separate file, ice_siov.c

To help with this, refactor the code in ice_sriov.c and split the generic
functionality out into separate files.

Reorganize code to make the non-implementation specific bits into new files
with the following general guidelines:

* ice_vf_lib.[ch]

Basic VF structures and accessors. This is where scheme-independent
code will reside.

* ice_virtchnl.[ch]

Virtchnl message handling. This is where the bulk of the logic for
processing messages from VFs using the virtchnl messaging scheme will
reside. This is separated from ice_vf_lib.c because it is somewhat
distinct and stand alone.

* ice_sriov.[ch]

Single Root IOV implementation, including initialization and the
routines for interacting with SR-IOV based netdev operations.

* (future) ice_siov.[ch]

Scalable IOV implementation.

The end goal is to make it easier to re-use the generic parts of the
virtualization logic while keeping separate the concerns of the Single Root
implementation.

In addition to the pure code moves, this series has a reset refactor which
clean up the functionality to make it easier to reuse the reset code. A new
ops table is introduced to make the VF reset logic more generic. The Single
Root specific details are implemented in ice_sriov.c. A future series
implementing Scalable IOV support will use this ops table to allow re-use of
the reset logic which is now in ice_vf_lib.c
