Beyond a specific version of firmware, there is no need to provide
override values to the firmware when setting PHY capabilities. In this
case, we do not need to indicate whether we're in Strict or Lenient Link
Mode.
In the case of translating capabilities to the configuration structure,
the module compliance enforcement is already correctly set by firmware,
so the extra code block is redundant.

Recent firmware supports a new "get PHY capabilities" mode
ICE_AQC_REPORT_DFLT_CFG which makes it unnecessary for the driver
to track and apply NVM based default link overrides.
If FW AQ API version supports it, use Report Default Configuration.
Add check function for Report Default Configuration support and update
accordingly.
Also change adv_phy_type_[lo|hi] to advert_phy_type[lo|hi] for
clarity.

Update ice_aq_get_rss_lut() and ice_aq_set_rss_lut() to take a new
structure ice_aq_get_set_rss_params instead of passing individual
parameters. This is done for 2 reasons:
1. Reduce the number of parameters passed to the functions.
2. Reduce the amount of change required if the arguments ever need to be
updated in the future.
Also, reduce duplicate code that was checking for an invalid vsi_handle

There is an issue with some NVMs where an already existent LLDP
filter is blocking the creation of a filter to allow LLDP packets
to be redirected to the default VSI for the interface. This is
blocking all LLDP functionality based in the kernel when the FW
LLDP agent is disabled (e.g. software based DCBx).
Implement the new AQ command to allow adding VSI destinations to
existent filters on NVM versions that support the new command.
The new lldp_fltr_ctrl AQ command supports Rx filters only, so the
code flow for adding filters to disable Tx of control frames will
remain intact.

If the driver initializes in safe mode, it will call
ice_set_safe_mode_caps. This results in clearing the capabilities
structures, in order to set them up for operating in safe mode, ensuring
many features are disabled.
This has a side effect of also clearing the capability bits that relate
to NVM update. The result is that the device driver will not indicate
support for unified update, even if the firmware is capable.
Fix this by adding the relevant capability fields to the list of values
we preserve. To simplify the code, use a common_cap structure instead of
a handful of local variables. To reduce some duplication of the
capability name, introduce a couple of macros used to restore the
capabilities values from the cached copy.

The grst_delay variable in ice_check_reset contains the maximum time
(in 100 msec units) that the driver will wait for a reset event to
transition to the Device Active state. The value is the sum of three
separate components:
1) The maximum time it may take for the firmware to process its
outstanding command before handling the reset request.
2) The value in RSTCTL.GRSTDEL (the delay firmware inserts between first
seeing the driver reset request and the actual hardware assertion).
3) The maximum expected reset processing time in hardware.
Referring to this total time as "grst_delay" is misleading and
potentially confusing to someone checking the code and cross-referencing
the hardware specification.
Fix this by renaming the variable to "grst_timeout", which is more
descriptive of its actual use.

Use the newly added pldmfw library to implement device flash update for
the Intel ice networking device driver. This support uses the devlink
flash update interface.
The main parts of the flash include the Option ROM, the netlist module,
and the main NVM data. The PLDM firmware file contains modules for each
of these components.
Using the pldmfw library, the provided firmware file will be scanned for
the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for
the main NVM module containing the primary device firmware, and
"fw.netlist" containing the netlist module.
The flash is separated into two banks, the active bank containing the
running firmware, and the inactive bank which we use for update. Each
module is updated in a staged process. First, the inactive bank is
erased, preparing the device for update. Second, the contents of the
component are copied to the inactive portion of the flash. After all
components are updated, the driver signals the device to switch the
active bank during the next EMP reset (which would usually occur during
the next reboot).
Although the firmware AdminQ interface does report an immediate status
for each command, the NVM erase and NVM write commands receive status
asynchronously. The driver must not continue writing until previous
erase and write commands have finished. The real status of the NVM
commands is returned over the receive AdminQ. Implement a simple
interface that uses a wait queue so that the main update thread can
sleep until the completion status is reported by firmware. For erasing
the inactive banks, this can take quite a while in practice.
To help visualize the process to the devlink application and other
applications based on the devlink netlink interface, status is reported
via the devlink_flash_update_status_notify. While we do report status
after each 4k block when writing, there is no real status we can report
during erasing. We simply must wait for the complete module erasure to
finish.
With this implementation, basic flash update for the ice hardware is
supported.

There isn't a case for 1G SGMII in ice_get_media_type() so add
the handling for it.
Also handle the special case where some direct attach
cables may report that they support 1G SGMII, but
that is erroneous since SGMII is supposed to be a
backplane media type (between a MAC and a PHY). If
the driver doesn't handle this special case then a
user could see the 'Port' in ethtool change from
'Direct attach Copper' to 'Backplane' when they have
forced the speed to 1G, but the cable hasn't changed.
Lastly, change ice_aq_get_phy_caps() to save the
module_type info if the function was called with
ICE_AQC_REPORT_TOPO_CAP. This call uses the media
information to populate the module_type. If no
media is present then the values in module_type

Adds functions to check for link override firmware support and get
the override settings for a port. The previously supported/default link
mode was strict mode.
In strict mode link is configured based on get PHY capabilities PHY types
with media.
Lenient mode is now the default link mode. In lenient mode the link is
configured based on get PHY capabilities PHY types without media. This
allows the user to configure link that the media does not report. Limit the
minimum supported link mode to 25G for devices that support 100G, and 1G
for devices that support less than 100G.
Default override is only supported in lenient mode. If default override
is supported and enabled, then default override values are used for
configuring speed and FEC. Default override provide persistent link
settings in the NVM.

Using the new ice_aq_list_caps and ice_parse_(dev|func)_caps functions,
replace ice_discover_caps with two functions that each take a pointer to
the dev_caps and func_caps structures respectively.
This makes the side effect of updating the hw->dev_caps and
hw->func_caps obvious from reading the implementation of the function.
Additionally, it opens the way for enabling reading of device
capabilities outside of the initialization flow. By passing in
a pointer, another caller will be able to read the capabilities without
modifying the HW capabilities structures.
As there are no other callers, it is safe to now remove
ice_aq_discover_caps and ice_parse_caps.

The ice_parse_caps function is used to convert the capability block data
coming from firmware into a structured format used by other parts of the
code.
The current implementation directly updates the hw->func_caps and
hw->dev_caps structures. It is directly called from within
ice_aq_discover_caps. This causes the discover_caps function to have the
side effect of modifying the HW capability structures, which is not
intuitive.
Split this function into ice_parse_dev_caps and ice_parse_func_caps.
These functions will take a pointer to the dev_caps and func_caps
respectively. Also create an ice_parse_common_caps for sharing the
capability logic that is common to device and function.
Doing so enables a future refactor to allow reading and parsing
capabilities into a local caps structure instead of modifying the
members of the HW structure directly.

The ice_discover_caps function is used to read the device and function
capabilities, updating the hardware capabilities structures with
relevant data.
The exact number of capabilities returned by the hardware is unknown
ahead of time. The AdminQ command will report the total number of
capabilities in the return buffer.
The current implementation involves requesting capabilities once,
reading this returned size, and then re-requested with that size.
This isn't really necessary. The firmware interface has a maximum size
of ICE_AQ_MAX_BUF_LEN. Firmware can never return more than
ICE_AQ_MAX_BUF_LEN / sizeof(struct ice_aqc_list_caps_elem) capabilities.
Avoid the retry loop by simply allocating a buffer of size
ICE_AQ_MAX_BUF_LEN. This is significantly simpler than retrying. The
extra allocation isn't a big deal, as it will be released after we
finish parsing the capabilities.

Flow Director allows for redirection based on ntuple rules. Rules are
programmed using the ethtool set-ntuple interface. Supported actions are
redirect to queue and drop.
Setup the initial framework to process Flow Director filters. Create and
allocate resources to manage and program filters to the hardware. Filters
are processed via a sideband interface; a control VSI is created to manage
communication and process requests through the sideband. Upon allocation of
resources, update the hardware tables to accept perfect filters.
