To enhance functionality, we now support reporting statistics through
the netdev-generic netlink (netdev-genl) queue stats interface. However,
this does not extend to all statistics, so a new field, qstat_offset,
has been introduced. This field determines which statistics should be
reported via netdev-genl queue stats.
Given that queue stats are retrieved individually per queue, it's
necessary for the virtnet_get_hw_stats() function to be capable of
fetching statistics for a specific queue.
As the document https://docs.kernel.org/next/networking/statistics.html#notes-for-driver-authors
We should not duplicate the stats which get reported via the netlink API in
ethtool. If the stats are for queue stat, that will not be reported by
ethtool -S.

That includes the \0 at the end. So the max length of the key name must

This commit introduces LED drivers for rtl8366rb, enabling LEDs to be
described in the device tree using the same format as qca8k. Each port
can configure up to 4 LEDs.
If all LEDs in a group use the default state "keep", they will use the
default behavior after a reset. Changing the brightness of one LED,
either manually or by a trigger, will disable the default hardware
trigger and switch the entire LED group to manually controlled LEDs.
Once in this mode, there is no way to revert to hardware-controlled LEDs
(except by resetting the switch).
Software triggers function as expected with manually controlled LEDs.

The necessity of asserting the reset on removal was previously
questioned, as DSA's own cleanup methods should suffice to prevent
traffic leakage[1].
When a driver has subdrivers controlled by devres, they will be
unregistered after the main driver's .remove is executed. If it asserts
a reset, the subdrivers will be unable to communicate with the hardware
during their cleanup. For LEDs, this means that they will fail to turn
off, resulting in a timeout error.

This switch family supports four LEDs for each of its six ports. Each
LED group is composed of one of these four LEDs from all six ports. LED
groups can be configured to display hardware information, such as link
activity, or manually controlled through a bitmap in registers
RTL8366RB_LED_0_1_CTRL_REG and RTL8366RB_LED_2_3_CTRL_REG.
After a reset, the default LED group configuration for groups 0 to 3
indicates, respectively, link activity, link at 1000M, 100M, and 10M, or
RTL8366RB_LED_CTRL_REG as 0x5432. These configurations are commonly used
for LED indications. However, the driver was replacing that
configuration to use manually controlled LEDs (RTL8366RB_LED_FORCE)
without providing a way for the OS to control them. The default
configuration is deemed more useful than fixed, uncontrollable turned-on
LEDs.
The driver was enabling/disabling LEDs during port_enable/disable.
However, these events occur when the port is administratively controlled
(up or down) and are not related to link presence. Additionally, when a
port N was disabled, the driver was turning off all LEDs for group N,
not only the corresponding LED for port N in any of those 4 groups. In
such cases, if port 0 was brought down, the LEDs for all ports in LED
group 0 would be turned off. As another side effect, the driver was
wrongly warning that port 5 didn't have an LED ("no LED for port 5").
Since showing the administrative state of ports is not an orthodox way
to use LEDs, it was not worth it to fix it and all this code was
dropped.
The code to disable LEDs was simplified only changing each LED group to
the RTL8366RB_LED_OFF state. Registers RTL8366RB_LED_0_1_CTRL_REG and
RTL8366RB_LED_2_3_CTRL_REG are only used when the corresponding LED
group is configured with RTL8366RB_LED_FORCE and they don't need to be
cleaned. The code still references an LED controlled by
RTL8366RB_INTERRUPT_CONTROL_REG, but as of now, no test device has
actually used it. Also, some magic numbers were replaced by macros.

Spectrum ASICs only support a single interrupt, that means that all the
events are handled by one IRQ (interrupt request) handler. Once an
interrupt is received, we schedule tasklet to handle events from EQ and
then schedule tasklets to handle completions from CQs. Tasklet runs in
softIRQ (software IRQ) context, and will be run on the same CPU which
scheduled it. That means that today we use only one CPU to handle all the
packets (both network packets and EMADs) from hardware.
This can be improved using NAPI. The idea is to use NAPI instance per
CQ, which is mapped 1:1 to DQ (RDQ or SDQ). NAPI poll method can be run
in kernel thread, so then the driver will be able to handle WQEs in several
CPUs. Convert the existing code to use NAPI APIs.
Add NAPI instance as part of 'struct mlxsw_pci_queue' and initialize it
as part of CQs initialization. Set the appropriate poll method and dummy
net device, according to queue number, similar to tasklet setup. For CQs
which are used for completions of RDQ, use Rx poll method and
'napi_dev_rx', which is set as 'threaded'. It means that Rx poll method
will run in kernel context, so several RDQs will be handled in parallel.
For CQs which are used for completions of SDQ, use Tx poll method and
'napi_dev_tx', this method will run in softIRQ context, as it is
recommended in NAPI documentation, as Tx packets' processing is short task.
Convert mlxsw_pci_cq_{rx,tx}_tasklet() to poll methods. Handle 'budget'
argument - ignore it in Tx poll method, as it is recommended to not limit
Tx processing. For Rx processing, handle up to 'budget' completions.
Return 'work_done' which is the amount of completions that were handled.
Handle the following cases:
1. After processing 'budget' completions, the driver still has work to do:
Return work-done = budget. In that case, the NAPI instance will be
polled again (without the need to be rescheduled). Do not re-arm the
queue, as NAPI will handle the reschedule, so we do not have to involve
hardware to send an additional interrupt for the completions that should
be processed.
2. Event processing has been completed:
Call napi_complete_done() to mark NAPI processing as completed, which
means that the poll method will not be rescheduled. Re-arm the queue,
as all completions were handled.
In case that poll method handled exactly 'budget' completions, return
work-done = budget -1, to distinguish from the case that driver still
has completions to handle. Otherwise, return the amount of completions
that were handled.

mlxsw will use NAPI for event processing in a next patch. As preparation,
add two dummy net devices and initialize them.
NAPI instance should be attached to net device. Usually each queue is used
by a single net device in network drivers, so the mapping between net
device to NAPI instance is intuitive. In our case, Rx queues are not per
port, they are per trap-group. Tx queues are mapped to net devices, but we
do not have a separate queue for each local port, several ports share the
same queue.
Use init_dummy_netdev() to initialize dummy net devices for NAPI.
To run NAPI poll method in a kernel thread, the net device which NAPI
instance is attached to should be marked as 'threaded'. It is
recommended to handle Tx packets in softIRQ context, as usually this is
a short task - just free the Tx packet which has been transmitted.
Rx packets handling is more complicated task, so drivers can use a
dedicated kernel thread to process them. It allows processing packets from
different Rx queues in parallel. We would like to handle only Rx packets in
kernel threads, which means that we will use two dummy net devices
(one for Rx and one for Tx). Set only one of them with 'threaded' as it
will be used for Rx processing. Do not fail in case that setting 'threaded'
fails, as it is better to use regular softIRQ NAPI rather than preventing
the driver from loading.
Note that the net devices are initialized with init_dummy_netdev(), so
they are not registered, which means that they will not be visible to user.
It will not be possible to change 'threaded' configuration from user
space, but it is reasonable in our case, as there is no another
configuration which makes sense, considering that user has no influence
on the usage of each queue.

Currently, for each CQE in CQ, we ring CQ doorbell, then handle RDQ and
ring RDQ doorbell. Finally we ring CQ arm doorbell - once per CQ tasklet.
The idea of ringing CQ doorbell before RDQ doorbell, is to be sure that
when we post new WQE (after RDQ is handled), there is an available CQE.
This was done because of a hardware bug as part of
commit c9ebea04cb ("mlxsw: pci: Ring CQ's doorbell before RDQ's").
There is no real reason to ring RDQ and CQ doorbells for each completion,
it is better to handle several completions and reduce number of ringings,
as access to hardware is expensive (time wise) and might take time because
of memory barriers.
A previous patch changed CQ tasklet to handle up to 64 Rx packets. With
this limitation, we can ring CQ and RDQ doorbells once per CQ tasklet.
The counters of the doorbells are increased by the amount of packets
that we handled, then the device will know for which completion to send
an additional event.
To avoid reordering CQ and RDQ doorbells' ring, let the tasklet to ring
also RDQ doorbell, mlxsw_pci_cqe_rdq_handle() handles the counter but
does not ring the doorbell.
Note that with this change there is no need to copy the CQE, as we ring CQ
doorbell only after Rx packet processing (which uses the CQE) is done.

We can get many completions in one interrupt. Currently, the CQ tasklet
handles up to half queue size completions, and then arms the hardware to
generate additional events, which means that in case that there were
additional completions that we did not handle, we will get immediately an
additional interrupt to handle the rest.
The decision to handle up to half of the queue size is arbitrary and was
determined in 2015, when mlxsw driver was added to the kernel. One
additional fact that should be taken into account is that while WQEs
from RDQ are handled, the CPU that handles the tasklet is dedicated for
this task, which means that we might hold the CPU for a long time.
Handle WQEs in smaller chucks, then arm CQ doorbell to notify the hardware
to send additional notifications. Set the chunk size to 64 as this number
is recommended using NAPI and the driver will use NAPI in a next patch.
Note that for now we use ARM doorbell to retrigger CQ tasklet, but with
NAPI it will be more efficient as software will reschedule the poll
method and we will not involve hardware for that.

This patch adds support to per-packet Tx hardware timestamp request to
AF_XDP zero-copy packet via XDP Tx metadata framework. Please note that
user needs to enable Tx HW timestamp capability via igc_ioctl() with
SIOCSHWTSTAMP cmd before sending xsk Tx hardware timestamp request.
Same as implementation in RX timestamp XDP hints kfunc metadata, Timer 0
(adjustable clock) is used in xsk Tx hardware timestamp. i225/i226 have
four sets of timestamping registers. *skb and *xsk_tx_buffer pointers
are used to indicate whether the timestamping register is already occupied.
Furthermore, a boolean variable named xsk_pending_ts is used to hold the
transmit completion until the tx hardware timestamp is ready. This is
because, for i225/i226, the timestamp notification event comes some time
after the transmit completion event. The driver will retrigger hardware irq
to clean the packet after retrieve the tx hardware timestamp.
Besides, xsk_meta is added into struct igc_tx_timestamp_request as a hook
to the metadata location of the transmit packet. When the Tx timestamp
interrupt is fired, the interrupt handler will copy the value of Tx hwts
into metadata location via xsk_tx_metadata_complete().
This patch is tested with tools/testing/selftests/bpf/xdp_hw_metadata
on Intel ADL-S platform. Below are the test steps and results.
Test Step 1: Run xdp_hw_metadata app
./xdp_hw_metadata <iface> > /dev/shm/result.log
Test Step 2: Enable Tx hardware timestamp

Test Step 5: Rerun Step 1-3 with 10s iperf3 as background traffic
Test Step 6: Rerun Step 1-4 with 10s iperf3 as background traffic
Based on iperf3 results below, the impact of holding tx completion to

net: intel: start The Great Code Dedup + Page Pool for iavf
Alexander Lobakin says:
Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and
libie) and switch iavf to Page Pool. Details are in the commit messages;
here's a summary:
Not a secret there's a ton of code duplication between two and more Intel
ethernet modules. Before introducing new changes, which would need to be
copied over again, start decoupling the already existing duplicate
functionality into a new module, which will be shared between several
Intel Ethernet drivers. The first name that came to my mind was
"libie" -- "Intel Ethernet common library". Also this sounds like
"lovelie" (-> one word, no "lib I E" pls) and can be expanded as
"lib Internet Explorer" :P
The "generic", pure-software part is placed separately, so that it can be
easily reused in any driver by any vendor without linking to the Intel
pre-200G guts. In a few words, it's something any modern driver does the
same way, but nobody moved it level up (yet).
The series is only the beginning. From now on, adding every new feature
or doing any good driver refactoring will remove much more lines than add
for quite some time. There's a basic roadmap with some deduplications
planned already, not speaking of that touching every line now asks:
"can I share this?". The final destination is very ambitious: have only
one unified driver for at least i40e, ice, iavf, and idpf with a struct
ops for each generation. That's never gonna happen, right? But you still
can at least try.
PP conversion for iavf lands within the same series as these two are tied
closely. libie will support Page Pool model only, so that a driver can't
use much of the lib until it's converted. iavf is only the example, the
rest will eventually be converted soon on a per-driver basis. That is
when it gets really interesting. Stay tech.

Someone complains the message appears continuously. This occurs
because the device is woken from UPS mode, and the driver re-loads
the firmware.
When the device enters runtime suspend and cable is unplugged, the
device would enter UPS mode. If the runtime resume occurs, and the
device is woken from UPS mode, the driver has to re-load the firmware
and causes the message. If someone wakes the device continuously, the
message would be shown continuously, too. Use dev_dbg to avoid it.
