Subject: [PATCH net-next 00/25][pull request] 100GbE Intel Wired LAN Driver Updates 2022-03-14

Jacob Keller says:

The ice_virtchnl_pf.c file has become a single place for a lot of
virtualization functionality. This includes most of the virtchnl message
handling, integration with kernel hooks like the .ndo operations, reset
logic, and more.

We are planning in the future to implement and support Scalable IOV in the
ice driver. To do this, much (but not all) of the code in ice_virtchnl_pf.c
will want to be reused.

Rather than dump all of the Scalable IOV implementation into
ice_virtchnl_pf.c it makes sense to house it in a separate file. But that
still leaves all of the Single Root IOV code littered among more generic
logic.

This series reorganizes 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 distinct
   and has a bulk of the processing code.

 * 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 goal is to make it easier to re-use parts of the virtualization logic
while separating concerns such as Single Root specific implementation
details.

In addition, this series has several minor cleanups and refactors we've
accumulated during this development cycle which help prepare the ice driver
for the Scalable IOV implementation.

This series builds on top of the recent hash table refactor work.

The following are changes since commit 5e7350e8a618ebfea0713b30986976fcbb90b8bb:
