With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.
After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.
The driver was invoking PCI helper functions like pci_save/restore_state(),
and pci_enable/disable_device(), which is not recommended.

With legacy PM hooks, it was the responsibility of a driver to manage PCI
states and also the device's power state. The generic approach is to let
PCI core handle the work.
ixgbe_suspend() calls __ixgbe_shutdown() to perform intermediate tasks.
__ixgbe_shutdown() modifies the value of "wake" (device should be wakeup
enabled or not), responsible for controlling the flow of legacy PM.
Since, PCI core has no idea about the value of "wake", new code for generic
PM may produce unexpected results. Thus, use "device_set_wakeup_enable()"
to wakeup-enable the device accordingly.

Remove legacy PM callbacks and use generic operations. With legacy code,
drivers were responsible for handling PCI PM operations like
pci_save_state(). In generic code, all these are handled by PCI core.
The generic suspend() and resume() are called at the same point the legacy
ones were called. Thus, it does not affect the normal functioning of the
driver.
__maybe_unused attribute is used with .resume() but not with .suspend(), as
.suspend() is called by .shutdown().

With the support of generic PM callbacks, drivers no longer need to use
legacy .suspend() and .resume() in which they had to maintain PCI states
changes and device's power state themselves. The required operations are
done by PCI core.
PCI drivers are not expected to invoke PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_set_power_state(), etc. Their tasks are completed by PCI core itself.

This is a port of i40e commit 705639572e8c ("i40e: need_wakeup flag might
not be set for Tx").
Quoting the original commit message:
"The need_wakeup flag for Tx might not be set for AF_XDP sockets that
are only used to send packets. This happens if there is at least one
outstanding packet that has not been completed by the hardware and we
get that corresponding completion (which will not generate an interrupt
since interrupts are disabled in the napi poll loop) between the time we
stopped processing the Tx completions and interrupts are enabled again.
In this case, the need_wakeup flag will have been cleared at the end of
the Tx completion processing as we believe we will get an interrupt from
the outstanding completion at a later point in time. But if this
completion interrupt occurs before interrupts are enable, we lose it and
should at that point really have set the need_wakeup flag since there
are no more outstanding completions that can generate an interrupt to
continue the processing. When this happens, user space will see a Tx
queue need_wakeup of 0 and skip issuing a syscall, which means will
never get into the Tx processing again and we have a deadlock."
As a result, packet processing stops. This patch introduces a fix for
this issue, by always setting the need_wakeup flag at the end of an
interrupt processing. This ensures that the deadlock will not happen.

Distribute the Tx queues evenly across all queue groups. This will
help the queues to get more equal sharing among the queues when all
are in use.
In the previous algorithm, the next queue group node will be picked up
only after the previous one filled with max children.
For example: if VSI is configured with 9 queues, the first 8 queues
will be assigned to queue group 1 and the 9th queue will be assigned to
queue group 2.
The 2 queue groups split the bandwidth between them equally (50:50).
The first queue group node will share the 50% bandwidth with all of
its children (8 queues). And the second queue group node will share
the entire 50% bandwidth with its only children.
The new algorithm will fix this issue.

If a user sets the value of the TX or RX descriptors to some non-default
value using 'ethtool -G' then we need to not overwrite the values when
we rebuild the VSI. The VSI rebuild could happen as a result of a user

then don't change the value.

During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability
register will be cleared. This can lead to issues when a VF is
assigned to a VM because in these cases the VF driver receives no
indication of the PF PCI error/reset and additionally it is incapable
of restoring the cleared flag in the hypervisor configuration space
without fully reinitializing the driver interrupt functionality.
Since the VF driver is unable to easily resolve this condition on its own,
restore the VF MSI-X flag during the PF PCI reset handling.

When the driver experiences a link event (especially link up)
there can be multiple events generated. Some of these are
link fault and still have a state of DOWN set. The problem
happens when the link comes UP during the PF driver handling
one of the LINK DOWN events. The status of the link is updated
and is now seen as UP, so when the actual LINK UP event comes,
the port information has already been updated to be seen as UP,
even though none of the UP activities have been completed.
After the link information has been updated in the link
handler and evaluated for MEDIA PRESENT, if the state
of the link has been changed to UP, treat the DOWN event
as an UP event since the link is now UP.

After a GLOBR, the link was broken so that a link
up situation was being seen as a link down.
The problem was that the rebuild process was updating
the port_info link status without doing any of the
other things that need to be done when link changes.
This was causing the port_info struct to have current
"UP" information so that any further UP interrupts
were skipped as redundant.
The rebuild flow should *not* be updating the port_info
struct link information, so eliminate this and leave
it to the link event handling code.

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

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

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

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.
