Add a KUnit test for the cs-amp-lib library. This has test cases
for cs_amp_get_efi_calibration_data() and cs_amp_write_cal_coeffs().
A KUNIT_STATIC_STUB_REDIRECT() has been added to
cs_amp_get_efi_variable() and cs_amp_write_cal_coeff() so that the
KUnit test can redirect these to test harness functions.
Much of the testing involves invoking the same function with different
parameters, i.e. the number of amps and the amp index within the array.
This uses parameterization rather than looping. The idea is to avoid
looping over configurations within one test case as that has a higher
chance of having a bug that doesn't actually test all the expected cases.
Having the test run exactly one configuration, and then tear-down, is less
prone to accidentally skipped configurations.

The indentation for ice_set_ctx and ice_write_rxq_ctx breaks the function
name after the return type. This style of breaking is used a lot throughout
the ice driver, even in cases where its not actually helpful for
readability. We no longer prefer this style of line splitting in the
driver, and new code is avoiding it.
Normally, I would leave this alone unless the actual function contents or
description needed updating. However, a future change is going to add
inverse functions for converting packed context to unpacked context
structures. To keep this code uniform with the existing set functions, fix
up the style to the modern format of keeping the type on the same line.

The functions used to pack the Tx and Rx context into the hardware format
rely on using BIT() and then subtracting 1 to get a bitmask. These
functions even have a comment about how x86 machines can't use this method
for certain widths because the SHL instructions will not work properly.
The Linux kernel already provides the GENMASK macro for generating a
suitable bitmask. Further, GENMASK is capable of generating the mask
including the shift_width. Since width is the total field width, take care
to subtract one to get the final bit position.
Since we now include the shifted bits as part of the mask, shift the source
value first before applying the mask.

In ice_common.c there are 4 functions used for converting the unpacked
software Tx and Rx context structure data into the packed format used by
hardware. These functions have extremely generic names:
* ice_write_byte
* ice_write_word
* ice_write_dword
* ice_write_qword
When I saw these function names my first thought was "write what? to
where?". Understanding what these functions do requires looking at the
implementation details. The functions take bits from an unpacked structure
and copy them into the packed layout used by hardware.
As part of live migration, we will want functions which perform the inverse
operation of reading bits from the packed layout and copying them into the
unpacked format. Naming these as "ice_read_byte", etc would be very
confusing since they appear to write data.
In preparation for adding this new inverse operation, rename the existing
functions to use the prefix "ice_pack_ctx_". This makes it clear that they
perform the bit packing while copying from the unpacked software context
structure to the packed hardware context.
The inverse operations can then neatly be named ice_unpack_ctx_*, clearly
indicating they perform the bit unpacking while copying from the packed
hardware context to the unpacked software context structure.

When initializing over virtchnl, the PF is required to pass a VSI ID to the
VF as part of its capabilities exchange. The VF driver reports this value
back to the PF in a variety of commands. The PF driver validates that this
value matches the value it sent to the VF.
Some hardware families such as the E700 series could use this value when
reading RSS registers or communicating directly with firmware over the
Admin Queue.
However, E800 series hardware does not support any of these interfaces and
the VF's only use for this value is to report it back to the PF. Thus,
there is no requirement that this value be an actual VSI ID value of any
kind.
The PF driver already does not trust that the VF sends it a real VSI ID.
The VSI structure is always looked up from the VF structure. The PF does
validate that the VSI ID provided matches a VSI associated with the VF, but
otherwise does not use the VSI ID for any purpose.
Instead of reporting the VSI number relative to the PF space, report a
fixed value of 1. When communicating with the VF over virtchnl, validate
that the VSI number is returned appropriately.
This avoids leaking information about the firmware of the PF state.
Currently the ice driver only supplies a VF with a single VSI. However, it
appears that virtchnl has some support for allowing multiple VSIs. I did
not attempt to implement this. However, space is left open to allow further
relative indexes if additional VSIs are provided in future feature
development. For this reason, keep the ice_vc_isvalid_vsi_id function in
place to allow extending it for multiple VSIs in the future.
This change will also simplify handling of live migration in a future
series. Since we no longer will provide a real VSI number to the VF, there
will be no need to keep track of this number when migrating to a new host.

The ice_vc_fdir_param_check() function validates that the VSI ID of the
virtchnl flow director command matches the VSI number of the VF. This is
already checked by the call to ice_vc_isvalid_vsi_id() immediately
following this.
This check is unnecessary since ice_vc_isvalid_vsi_id() already confirms
this by checking that the VSI ID can locate the VSI associated with the VF
structure.
Furthermore, a following change is going to refactor the ice driver to
report VSI IDs using a relative index for each VF instead of reporting the
PF VSI number. This additional check would break that logic since it
enforces that the VSI ID matches the VSI number.
Since this check duplicates the logic in ice_vc_isvalid_vsi_id() and gets
in the way of refactoring that logic, remove it.

The ice_vc_isvalid_q_id() function takes a VSI index and a queue ID. It
looks up the VSI from its index, and then validates that the queue number
is valid for that VSI.
The VSI ID passed is typically a VSI index from the VF. This VSI number is
validated by the PF to ensure that it matches the VSI associated with the
VF already.
In every flow where ice_vc_isvalid_q_id() is called, the PF driver already
has a pointer to the VSI associated with the VF. This pointer is obtained
using ice_get_vf_vsi(), rather than looking up the VSI using the index sent
by the VF.
Since we already know which VSI to operate on, we can modify
ice_vc_isvalid_q_id() to take a VSI pointer instead of a VSI index. Pass
the VSI we found from ice_get_vf_vsi() instead of re-doing the lookup. This
removes some unnecessary computation and scanning of the VSI list.
It also removes the last place where the driver directly used the VSI
number from the VF. This will pave the way for refactoring to communicate
relative VSI numbers to the VF instead of absolute numbers from the PF
space.
