In some cases of resetting a VF, the PF would like to first notify the
VF that a reset is impending. This is currently done via
ice_vc_notify_vf_reset. A wrapper to ice_reset_vf, ice_vf_reset_vf, is
used to call this function first before calling ice_reset_vf.
In fact, every single call to ice_vc_notify_vf_reset occurs just prior
to a call to ice_vc_reset_vf.
Now that ice_reset_vf has flags, replace this separate call with an
ICE_VF_RESET_NOTIFY flag. This removes an unnecessary exported function
of ice_vc_notify_vf_reset, and also makes there be a single function to
reset VFs (ice_reset_vf).

The ice_reset_vf function takes a boolean parameter which indicates
whether or not the reset is due to a VFLR event.
This is somewhat confusing to read because readers must interpret what
"true" and "false" mean when seeing a line of code like
"ice_reset_vf(vf, false)".
We will want to add another toggle to the ice_reset_vf in a following
change. To avoid proliferating many arguments, convert this function to
take flags instead. ICE_VF_RESET_VFLR will indicate if this is a VFLR
reset. A value of 0 indicates no flags.
One could argue that "ice_reset_vf(vf, 0)" is no more readable than
"ice_reset_vf(vf, false)".. However, this type of flags interface is
somewhat common and using 0 to mean "no flags" makes sense in this
context. We could bother to add a define for "ICE_VF_RESET_PLAIN" or
something similar, but this can be confusing since its not an actual bit
flag.
This paves the way to add another flag to the function in a following

The ice driver currently supports virtualization using Single Root IOV,
with code in the ice_sriov.c file. In the future, we plan to also
implement support for Scalable IOV, which uses slightly different
hardware implementations for some functionality.
To eventually allow this, we introduce a new ice_vf_ops structure which
will contain the basic operations that are different between the two IOV
implementations. This primarily includes logic for how to handle the VF
reset registers, as well as what to do before and after rebuilding the
VF's VSI.
Implement these ops structures and call the ops table instead of
directly calling the SR-IOV specific function. This will allow us to
easily add the Scalable IOV implementation in the future. Additionally,
it helps separate the generalized VF logic from SR-IOV specifics. This
change allows us to move the reset logic out of ice_sriov.c and into
ice_vf_lib.c without placing any Single Root specific details into the
generic file.

Introduce the ice_vf_lib.c file along with the ice_vf_lib.h and
ice_vf_lib_private.h header files.
These files will house the generic VF structures and access functions.
Move struct ice_vf and its dependent definitions into this new header
file.
The ice_vf_lib.c is compiled conditionally on CONFIG_PCI_IOV. Some of
its functionality is required by all driver files. However, some of its
functionality will only be required by other files also conditionally
compiled based on CONFIG_PCI_IOV.
Declaring these functions used only in CONFIG_PCI_IOV files in
ice_vf_lib.h is verbose. This is because we must provide a fallback
implementation for each function in this header since it is included in
files which may not be compiled with CONFIG_PCI_IOV.
Instead, introduce a new ice_vf_lib_private.h header which verifies that
CONFIG_PCI_IOV is enabled. This header is intended to be directly
included in .c files which are CONFIG_PCI_IOV only. Add a #error
indication that will complain if the file ever gets included by another
C file on a kernel with CONFIG_PCI_IOV disabled. Add a comment
indicating the nature of the file and why it is useful.
This makes it so that we can easily define functions exposed from
ice_vf_lib.c into other virtualization files without needing to add
fallback implementations for every single function.
This begins the path to separate out generic code which will be reused
by other virtualization implementations from ice_sriov.h and ice_sriov.c

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.

struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.
Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.
Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

On Renoir, vcn ring test failed on the second time insmod in the reload
test. After investigation, it proves that vcn only can disable dpg under

mode is for dec/enc).

IEEE_8021QAZ_MAX_TCS is defined in include/uapi/linux/dcbnl.h, which is
included by net/dcbnl.h. Then, linux/netdevice.h conditionally includes
net/dcbnl.h if CONFIG_DCB is enabled.
Therefore, when CONFIG_DCB is disabled, this indirect dependency is
broken.
There isn't a good reason to include net/dcbnl.h headers into the ocelot
switch library which exports low-level hardware API, so replace
IEEE_8021QAZ_MAX_TCS with OCELOT_NUM_TC which has the same value.
