Currently merge_config.sh will unconditionally warn if a fragment overrides
any already set symbol. This is generally desirable but is inconvenient in
cases where we want to create a fragment which disables unwanted options in
the base configuration, for example when attempting to produce a smaller
version of another configuration.
Add an option -Q which will suppress these warnings.

There was a problem reported to us where the addition of a VF with an IPv6
address ending with a particular sequence would cause the parent device on
the PF to no longer be able to respond to neighbor discovery packets.
In this case, we had an ovs-bridge device living on top of a VLAN, which
was on top of a PF, and it would not be able to talk anymore (the neighbor
entry would expire and couldn't be restored).
The root cause of the issue is that if the PF is asked to be in IFF_PROMISC
mode (promiscuous mode) and it had an ipv6 address that needed the
33:33:ff:00:00:04 multicast address to work, then when the VF was added
with the need for the same multicast address, the VF would steal all the
traffic destined for that address.
The ice driver didn't auto-subscribe a request of IFF_PROMISC to the
"multicast replication from other port's traffic" meaning that it won't get
for instance, packets with an exact destination in the VF, as above.
The VF's IPv6 address, which adds a "perfect filter" for 33:33:ff:00:00:04,
results in no packets for that multicast address making it to the PF (which
is in promisc but NOT "multicast replication").
The fix is to enable "multicast promiscuous" whenever the driver is asked
to enable IFF_PROMISC, and make sure to disable it when appropriate.

Pull clocksource watchdog changes from Paul McKenney:
o Improvements to clocksource-watchdog console messages.
o Loosening of the clocksource-watchdog skew criteria to match
those of NTP (500 parts per million, relaxed from 400 parts
per million). If it is good enough for NTP, it is good enough
for the clocksource watchdog.
o Suspend clocksource-watchdog checking temporarily when high
memory latencies are detected. This avoids the false-positive
clock-skew events that have been seen on production systems
running memory-intensive workloads.
o On systems where the TSC is deemed trustworthy, use it as the
watchdog timesource, but only when specifically requested using
the tsc=watchdog kernel boot parameter. This permits clock-skew
events to be detected, but avoids forcing workloads to use the
slow HPET and ACPI PM timers. These last two timers are slow
enough to cause systems to be needlessly marked bad on the one
hand, and real skew does sometimes happen on production systems
running production workloads on the other. And sometimes it is
the fault of the TSC, or at least of the firmware that told the
kernel to program the TSC with the wrong frequency.
o Add a tsc=revalidate kernel boot parameter to allow the kernel
to diagnose cases where the TSC hardware works fine, but was told
by firmware to tick at the wrong frequency. Such cases are rare,
but they really have happened on production systems.

Fix a regression introduced by commit 9946e39fe8d0 ("ACPI: resource: skip
IRQ override on AMD Zen platforms") on MAINGEAR Vector Pro 2 systems, which
causes the built-in keyboard to not work. This restores the functionality
by adding an IRQ override.
No other IRQs were being overridden before, so this should be all that is
needed for these systems. I have personally tested this on the 15" model
(MG-VCP2-15A3070T), and I have confirmation that the issue is present on
the 17" model (MG-VCP2-17A3070T).

Add a pair of macros for exporting functions only if CONFIG_PM
is enabled.
The naming follows the style of the standard EXPORT_SYMBOL_*()
macros that they replace.
Sometimes a module wants to export PM functions directly to other
drivers, not a complete struct dev_pm_ops. A typical example is
where a core library exports the generic (shared) implementation
and calling code wraps one or more of these in custom code.

Alexander Lobakin says:
====================
The set grew from the poor performance of %BPF_F_TEST_XDP_LIVE_FRAMES
when the ice-backed device is a sender. Initially there were around
3.3 Mpps / thread, while I have 5.5 on skb-based pktgen ...
After fixing 0005 (0004 is a prereq for it) first (strange thing nobody
noticed that earlier), I started catching random OOMs. This is how 0002
(and partially 0001) appeared.
0003 is a suggestion from Maciej to not waste time on refactoring dead
lines. 0006 is a "cherry on top" to get away with the final 6.7 Mpps.
4.5 of 6 are fixes, but only the first three are tagged, since it then
starts being tricky. I may backport them manually later on.
TL;DR for the series is that shortcuts are good, but only as long as
they don't make the driver miss important things. %XDP_TX is purely
driver-local, however .ndo_xdp_xmit() is not, and sometimes assumptions
can be unsafe there.
With that series and also one core code patch[0], "live frames" and
xdp-trafficgen are now safe'n'fast on ice (probably more to come).

After the recent mbuf changes, ice_xmit_xdp_ring() became a 3-liner.
It makes no sense to keep it global in a different file than its caller.
Move it just next to the sole call site and mark static. Also, it
doesn't need a full xdp_convert_frame_to_buff(). Save several cycles
and fill only the fields used by __ice_xmit_xdp_ring() later on.
Finally, since it doesn't modify @xdpf anyhow, mark the argument const
to save some more (whole -11 bytes of .text! :D).
Thanks to 1 jump less and less calcs as well, this yields as many as
6.7 Mpps per queue. `xdp.data_hard_start = xdpf` is fully intentional
again (see xdp_convert_buff_to_frame()) and just works when there are
no source device's driver issues.

As already mentioned, freeing any &xdp_frame via page_frag_free() is
wrong, as it assumes the frame is backed by either an order-0 page or
a page with no "patrons" behind them, while in fact frames backed by
Page Pool can be redirected to a device, which's driver doesn't use it.
Keep storing a pointer to the raw buffer and then freeing it
unconditionally via page_frag_free() for %XDP_TX frames, but introduce
a separate type in the enum for frames coming through .ndo_xdp_xmit(),
and free them via xdp_return_frame_bulk(). Note that saving xdpf as
xdp_buff->data_hard_start is intentional and is always true when
everything is configured properly.
After this change, %XDP_REDIRECT from a Page Pool based driver to ice
becomes zero-alloc as it should be and horrendous 3.3 Mpps / queue
turn into 6.6, hehe.
Let it go with no "Fixes:" tag as it spans across good 5+ commits and
can't be trivially backported.

When queueing frames from a Page Pool for redirecting to a device backed
by the ice driver, `perf top` shows heavy load on page_alloc() and
page_frag_free(), despite that on a properly working system it must be
fully or at least almost zero-alloc. The problem is in fact a bit deeper
and raises from how ice cleans up completed Tx buffers.
The story so far: when cleaning/freeing the resources related to
a particular completed Tx frame (skbs, DMA mappings etc.), ice uses some
heuristics only without setting any type explicitly (except for dummy
Flow Director packets, which are marked via ice_tx_buf::tx_flags).
This kinda works, but only up to some point. For example, currently ice
assumes that each frame coming to __ice_xmit_xdp_ring(), is backed by
either plain order-0 page or plain page frag, while it may also be
backed by Page Pool or any other possible memory models introduced in
future. This means any &xdp_frame must be freed properly via
xdp_return_frame() family with no assumptions.
In order to do that, the whole heuristics must be replaced with setting
the Tx buffer/frame type explicitly, just how it's always been done via
an enum. Let us reuse 16 bits from ::tx_flags -- 1 bit-and instr won't
hurt much -- especially given that sometimes there was a check for
%ICE_TX_FLAGS_DUMMY_PKT, which is now turned from a flag to an enum
member. The rest of the changes is straightforward and most of it is
just a conversion to rely now on the type set in &ice_tx_buf rather than
to some secondary properties.
For now, no functional changes intended, the change only prepares the
ground for starting freeing XDP frames properly next step. And it must
be done atomically/synchronously to not break stuff.

The tagged commit started sending %XDP_TX frames from XSk Rx ring
directly without converting it to an &xdp_frame. However, when XSk is
enabled on a queue pair, it has its separate Tx cleaning functions, so
neither ice_clean_xdp_irq() nor ice_unmap_and_free_tx_buf() ever happens
there.
Remove impossible branches in order to reduce the diffstat of the
upcoming change.

Sometimes, under heavy XDP Tx traffic, e.g. when using XDP traffic
generator (%BPF_F_TEST_XDP_LIVE_FRAMES), the machine can catch OOM due
to the driver not freeing all of the pages passed to it by
.ndo_xdp_xmit().
Turned out that during the development of the tagged commit, the check,
which ensures that we have a free descriptor to queue a frame, moved
into the branch happening only when a buffer has frags. Otherwise, we
only run a cleaning cycle, but don't check anything.
ATST, there can be situations when the driver gets new frames to send,
but there are no buffers that can be cleaned/completed and the ring has
no free slots. It's very rare, but still possible (> 6.5 Mpps per ring).
The driver then fills the next buffer/descriptor, effectively
overwriting the data, which still needs to be freed.
Restore the check after the cleaning routine to make sure there is a
slot to queue a new frame. When there are frags, there still will be a
separate check that we can place all of them, but if the ring is full,
there's no point in wasting any more time.
(minor: make `!ready_frames` unlikely since it happens ~1-2 times per
billion of frames)

xdp_tx_active is used to indicate whether an XDP ring has any %XDP_TX
frames queued to shortcut processing Tx cleaning for XSk-enabled queues.
When !XSk, it simply indicates whether the ring has any queued frames in
general.
It gets increased on each frame placed onto the ring and counts the
whole frame, not each frag. However, currently it gets decremented in
ice_clean_xdp_tx_buf(), which is called per each buffer, i.e. per each
frag. Thus, on completing multi-frag frames, an underflow happens.
Move the decrement to the outer function and do it once per frame, not
buf. Also, do that on the stack and update the ring counter after the
loop is done to save several cycles.
XSk rings are fine since there are no frags at the moment.

If the chip can have an LED, register a struct led_classdev and enable
hardware-controlled blinking. When the chip is not transmitting or
receiving anything the LED is off. Otherwise the LED will blink
faster or slower according to the throughput.
The LED can be controlled from userspace by writing 0, 1, or 2 to
/sys/class/leds/rtl8xxxu-usbX-Y/brightness:
0 - solid off.
1 - solid on.
2 - hardware-controlled blinking.
In this patch none of the chips advertise having an LED. That will be

Driver can prepare pkt_list for firmware that only uses them to send out
the packets in specific situations. To understand the usage of current
status, and to check if there is leakage problem, dump bitmap and the
indices used by certain function.
An example looks like:
map:
...
pkt_ofld: 3f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...
[SCAN 0]: 3
[SCAN 1]: 4
[SCAN 3]: 5
VIF [0] xx:xx:xx:xx:xx:xx
...
pkt_ofld[GENERAL]: 0 1 2

For upcoming firmware, driver needs to do packet offload to firmware to
ensure LPS protocol work properly, so we update current connection and
disconnect flow to maintain packet offload flow, and integrate with
current WoWLAN flow which also needs packet offload.

When driver fails to send H2C to firmware for pkt-offload, we should not
update the pkt_list of driver, and need to release allocated pkt index to
avoid wrong mapping between driver and firmware.

Building BPF selftests out of srctree fails with:
make: *** No rule to make target '/linux-build//ima_setup.sh', needed by 'ima_setup.sh'. Stop.
The culprit is the rule that defines convenient shorthands like
"make test_progs", which builds $(OUTPUT)/test_progs. These shorthands
make sense only for binaries that are built though; scripts that live
in the source tree do not end up in $(OUTPUT).
Therefore drop $(TEST_PROGS) and $(TEST_PROGS_EXTENDED) from the rule.
The issue exists for a while, but it became a problem only after commit
d68ae4982cb7 ("selftests/bpf: Install all required files to run selftests"),
which added dependencies on these scripts.

To debug channel concurrency more centrally, we add a new debug flag,
RTW89_DBG_CHAN, for channel related things, especially channel concurrency.
Then, we change MCC (multi-channel concurrency) C2H (chip to host packets)
debug flag to it.
Besides, refine debug logs to show TSF in u64 directly.

RXI300 is a HW design to maintain stuffs across BUS, e.g. AXI, AHB, APB.
It will feedback an error when host does an invalid BUS operation.
For example,
* BUS master request without power/clock on.
* host reads/writes/accesses an invalid address.
They might lead to problems such as BUS timeout, platform hang, etc. So,
once if RXI300 feedback an error, it notifies that driver need a L2 SER
(system error recovery) to reset things.
Previously, driver did not parse the error scenario for RXI300. We add
it and assign a corresponding error code which will make SER flow do L2
reset.

Only 8852C chip has valid pages on RTW89_DBG_SEL_MAC_30. To other chips,
this section is an address hole. It will lead to crash if trying to access
this section on chips except for 8852C. So, we avoid that.

Originally, rtw89_mac_port_tsf_sync() contains randomization logic
internally. However, not all situation, we need the randomization.
So, split out the generic part from it. And, make the full logic of
original one contained in rtw89_mac_port_tsf_sync_rand(). It will
still be used by its original caller as before. Then, the generic
one will be used in MCC (multi-channel concurrency) management flow.
MCC will implement its logic to decide the offset for TSF sync.

The origin code will enable TDMA WL:BT = 50:50 to prevent Wi-Fi
throughput suddenly drop to 0 in the moment while A2DP pause.
And this protection just a short moment, and will turn to Bluetooth
idle case when A2DP turn into sniff mode. But the raspberryPI simulated
A2DP device will not turn into sniff mode. So the protection will bring
the throughput drop.
