Create a common structure to contain all different versions of the
tx_power_cmd instead of making a union of the different structs
everywhere we need them. Also move the common part of these structs
into a separate structure (instead of reusing v3) and leave the
per_chain_restriction part out of the common part, because this will
change in version 6 of the command (which will be added soon).
While at it, rename per_chain_restriction to per_chain to shorten it.

On newer hardware, we have the full checksum, so use it to report
CHECKSUM_COMPLETE and avoid the protocol specific hardware parsing.
Note that the hardware already parses/removes the SNAP header, so
we actually literally get what we need to report to the stack, as
we're expected to checksum everything after the L2 header (which
is translated/added by mac80211).

The the driver prevents new Tx from being sent during the remove-station
flow is by invalidating the fw_id_to_mac_id rcu of that station.
However, if there was any Tx still in-flight (tx-cmd was sent but the
ba-notif wasn't received yet) the ba-response to those frames is simply
ignored without actually reclaiming anything. This later causes the
driver to think that that some of the station's queues aren't empty when
in practice they are which causes errors in the station remove flow.
Fix this by performing the tx-reclaim also if the rcu is invalid. any DB
that can't be updated due to this is not very important at this stage
since the station is about to be removed soon anyways.

A FTM responder may do PASN authentication with unassociated stations
to allow secure ranging. In this case, the driver will add an internal
station and install the TK so the FW will accept protected FTM
request frames from this station and will send a protected FTM
response frame.
In addition, the driver needs to configure the HLTK to the FW so
the FW can derive the secure LTF bits. This is left for a later
patch since it is not yet supported by the FW.

According to [1], platform firmware may not properly power manage the
device during shutdown. I did some expirements and putting the device to
D3 can workaround the issue.
So let's power cycle the device by putting the device to D3 at shutdown
to prevent the issue from happening.

Since commit c330fb1ddc ("XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information.")
Xen is using the chip_data pointer for storing IRQ specific data. When
running as a HVM domain this can result in problems for legacy IRQs, as
those might use chip_data for their own purposes.
Use a local array for this purpose in case of legacy IRQs, avoiding the
double use.

Commit 387caf0b75 ("iommu/amd: Treat per-device exclusion

the 'flags' field in IVMD (struct ivmd_header) when the I/O
virtualization memory definition is associated with the
exclusion range entry. This leads to the corrupted IVMD table
(incorrect checksum). The kdump kernel reports the invalid checksum:
ACPI BIOS Warning (bug): Incorrect checksum in table [IVRS] - 0x5C, should be 0x60 (20200717/tbprint-177)

When driver has been converted to the bitmap API the non-bitmap functions
started behaving differently on 32-bit BE architectures since the bytes in
two consequent unsigned longs are in different order in comparison to byte
array. Hence if the chip had had more than 32 lines the memset() call over
it would have not set up upper lines correctly.
Although it's currently a theoretical case (no supported chips of this type
has 32+ lines), it's better to provide a clean code to avoid people thinking
this is okay and potentially producing not fully working things.
