The driver is supposed to avoid entering LPS (power saving) when there
is beacon loss, but only RTL8822C detects the beacon loss (because it
has beacon filtering in the firmware).
Detect beacon loss with the other chips by checking if we received less
than half the expected number of beacons in the last 2-second interval.
This gets rid of the occasional "failed to get tx report from firmware"
warnings with RTL8821AU. It may also avoid some disconnections.

"ls" meaning "last segment". Without this RTL8812AU can't upload the

Also tested with RTL8822CU, RTL8812BU, RTL8811CU, RTL8723DU, RTL8811AU.

RTL8812AU uses one set of TX power tracking tables for RFE 3, and
another set for everything else.
Move pwr_track_tbl from struct rtw_chip_info to struct rtw_rfe_def in
order to load the right set of tables for each RFE (RF front end) type.

All the chips supported so far have a TX page size of 128 bytes.
Change the type of the page_size member of struct rtw_chip_info from u8
to u16 in order to support RTL8821AU (page size of 256 bytes) and
RTL8812AU (page size of 512 bytes). Also change the types of several
related variables and function parameters from u8 to u16.
The TX page size is used, among other things, to construct the beacon,
null data, QOS null data, and PS poll templates which are uploaded to
the chip's reserved page. Each template needs to be aligned on a
multiple of the TX page size. Power saving can't work if the TX page
size is wrong.

txagc_remnant_ofdm member of struct rtw_dm_info should be different for
each RF path, so make it an array of size RTW_RF_PATH_MAX (4).
Until now all the chips using this had only one RF path, but RTL8812AU
has two, and RTL8814AU has four.

RTL8811AU fails to perform the 4-way handshake when the AP is too far
because it transmits the EAPOL frames at MCS9 and when that doesn't
work it retries 48 times with the same rate, to no avail.
Retrying 48 times with the same rate seems pointless. Set the
appropriate field in the TX descriptor to allow it to use lower rates
when retrying.
Set it for RTL8723D and RTL8703B because they interpret this field the
same way as RTL8811A.
The newer RTL8822C, RTL8822B, RTL8821C seem to interpret this field in
the TX descriptor differently, so leave it alone for those chips.
Tested with RTL8811AU and RTL8723DU.

self-powered devices
PD3.1 spec ("8.3.3.3.3 PE_SNK_Wait_for_Capabilities State") mandates
that the policy engine perform a hard reset when SinkWaitCapTimer
expires. Instead the code explicitly does a GET_SOURCE_CAP when the
timer expires as part of SNK_WAIT_CAPABILITIES_TIMEOUT. Due to this the
following compliance test failures are reported by the compliance tester
(added excerpts from the PD Test Spec):
* COMMON.PROC.PD.2#1:
The Tester receives a Get_Source_Cap Message from the UUT. This
message is valid except the following conditions: [COMMON.PROC.PD.2#1]
a. The check fails if the UUT sends this message before the Tester
has established an Explicit Contract
...
* TEST.PD.PROT.SNK.4:
...
4. The check fails if the UUT does not send a Hard Reset between
tTypeCSinkWaitCap min and max. [TEST.PD.PROT.SNK.4#1] The delay is
between the VBUS present vSafe5V min and the time of the first bit
of Preamble of the Hard Reset sent by the UUT.
For the purpose of interoperability, restrict the quirk introduced in
https://lore.kernel.org/all/20240523171806.223727-1-sebastian.reichel@collabora.com/

Setting of channel and TX power depend on channel contexts, but original
code cannot handle combination of MCC (multi-channel concurrency) and MLO
well. So according to active interfaces, we generate a table for current
channel contexts. And then based on entity mode, we get the corresponding
channel context to apply during channel or TX power setting. When MLO is
supported, there will be dual-PHY and we will apply the channel context of
the 2nd link to the 2nd PHY.

Fix a boot hang issue triggered when a USB3 device is incorrectly assumed
to be tunneled over USB4, thus attempting to create a device link between
the USB3 "consumer" device and the USB4 "supplier" Host Interface before
the USB4 side is properly bound to a driver.
This could happen if xhci isn't capable of detecting tunneled devices,
but ACPI tables contain all info needed to assume device is tunneled.
i.e. udev->tunnel_mode == USB_LINK_UNKNOWN.
It turns out that even for actual tunneled USB3 devices it can't be
assumed that the thunderbolt driver providing the tunnel is loaded
before the tunneled USB3 device is created.
The tunnel can be created by BIOS and remain in use by thunderbolt/USB4
host driver once it loads.
Solve this by making the device link "stateless", which doesn't create
a driver presence order dependency between the supplier and consumer
drivers.
It still guarantees correct suspend/resume and shutdown ordering.

To set channel well for combination of MCC (multi-channel concurrency) and
impending MLO support, we need a method to manage relation between active
interfaces and channel contexts. If an interface owns at least one active
link, we call it an active interface. We add a list to manage active ones.
Basically, the list follows the active order except for the below case. To
be compatible with legacy behavior, the first interface that owns the first
channel context will put at the first entry in the list when recalculating.
Besides, MCC can also select and fill roles based on the above active list.

During the aborting of a command, the software receives a command
completion event for the command ring stopped, with the TRB pointing
to the next TRB after the aborted command.
If the command we abort is located just before the Link TRB in the
command ring, then during the 'command ring stopped' completion event,
the xHC gives the Link TRB in the event's cmd DMA, which causes a
mismatch in handling command completion event.
To address this situation, move the 'command ring stopped' completion
event check slightly earlier, since the specific command it stopped
on isn't of significant concern.

KASAN reports the following UAF. The metadata_dst, which is used to
store the SCI value for macsec offload, is already freed by
metadata_dst_free() in macsec_free_netdev(), while driver still use it
for sending the packet.
To fix this issue, dst_release() is used instead to release
metadata_dst. So it is not freed instantly in macsec_free_netdev() if
still referenced by skb.

Bonding only supports native XDP for specific modes, which can lead to
confusion for users regarding why XDP loads successfully at times and
fails at others. This patch enhances error handling by returning detailed
error messages, providing users with clearer insights into the specific
reasons for the failure when loading native XDP.

Instead of flushing and reloading the auth session for every transaction

Both drivers use I/O port accesses without declaring a dependency on
CONFIG_HAS_IOPORT. For sbc8360_wdt this causes a compile error on UML
once inb()/outb() helpers become conditional.
For sbc7240_wdt this causes no such errors with UML because this driver
depends on both x86_32 and !UML. Nevertheless add HAS_IOPORT as
a dependency for both drivers to be explicit and drop the !UML
dependency for sbc7240_wdt as it is now redundant since UML implies no
HAS_IOPORT.

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them unconditionally. Some 8250 serial drivers support
MMIO only use, so fence only the parts requiring I/O ports and print an
error message if a device can't be supported with the current
configuration.

detected at runtime, warn if this isn't taken when HAS_IOPORT is not
defined.
There is also a direct and hard coded use in cirrus.c which according to
the comment is only necessary during resume. Let's just skip this as
for example s390 which doesn't have I/O port support also doesen't
support suspend/resume.

commit 7c210ca5a2d7 ("drm/amdgpu: handle default profile on on devices without fullscreen 3D")
While everything is set correctly, this caused the profile to be
reported incorrectly because both the powersave and fullscreen3d bits
were set in the mask and when the driver prints the profile, it looks
for the first bit set.

Empirically we can confirm that the former allocates 152 bytes for the
table, while the latter memsets the 168 large block.
Root cause appears that when GPU metrics tables for v2_4 parts were added
it was not considered to enlarge the table to fit.
The fix in this patch is rather "brute force" and perhaps later should be
done in a smarter way, by extracting and consolidating the part version to
size logic to a common helper, instead of brute forcing the largest
possible allocation. Nevertheless, for now this works and fixes the out of
bounds write.

The offending commit exposes a hang with lid close/open behavior.
Both issues seem to be related to ODM 2:1 mode switching, so there
is another issue generic to that sequence that needs to be
