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.

The long term goal is to re-organize the code such that generic re-usable
code is split into separate files. The ice_sriov.c file would end up
containing all of the Single Root IOV implementation specific details, while
ice_vf_lib.[ch] and ice_virtchnl.[ch] contain the generic pieces.

As a first step, notice that ice_sriov.c currently does not contain much of
the SR-IOV implementation. This is housed primarily in ice_virtchnl_pf.c

The code in ice_sriov.c is really generic and relates to the VF mailbox,
including mailbox overflow detection.

Rename ice_sriov.c to ice_vf_mbx.c, and then rename ice_virtchnl_pf.c to
ice_sriov.c

A later series will finish the refactor by splitting ice_sriov.c into
multiple files, moving the generic code into ice_vf_lib.c and ice_virtchnl.c

To prepare for that series, perform some basic cleanup and other refactors
that we've accumulated during this development cycle.

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

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: use ice_is_vf_trusted helper function
  ice: log an error message when eswitch fails to configure
  ice: cleanup error logging for ice_ena_vfs
  ice: move ice_set_vf_port_vlan near other .ndo ops
  ice: refactor spoofchk control code in ice_sriov.c
  ice: rename ICE_MAX_VF_COUNT to avoid confusion
  ice: remove unused definitions from ice_sriov.h
  ice: convert vf->vc_ops to a const pointer
  ice: remove circular header dependencies on ice.h
  ice: rename ice_virtchnl_pf.c to ice_sriov.c
  ice: rename ice_sriov.c to ice_vf_mbx.c
