In the rtl8366rb driver there are some jam tables which contain
undocumented values.
While trying to understand what these tables actually do,
I noticed a discrepancy in how one of those was treated.
Most of them were plain u16 arrays, while the ethernet one was
an u16 matrix.
By looking at the vendor's droplets of source code these tables came from,
I found out that they were all originally u16 matrixes.
This commit standardizes the jam tables, turning them all into
jam_tbl_entry arrays. Each entry contains 2 u16 values.
This change makes it easier to understand how the jam tables are used
and also makes it possible for a single function to handle all of them,
removing some duplicated code.

mlx5 devlink traps support
Add support for devlink traps [1] reporting in mlx5,
mlx5 will also report/trap packets filtered due to dest mac steering miss
The first patch in the series defines the new DMAC trap type in devlink
for this purpose.
Other patches in the series are mlx5 only and they gradually traps support.
Supported traps:
DMAC: Drops due to destination MAC not configured in the MAC table
VLAN: Drops due to vlan not configured in the vlan table
Design note:
devlink instance is managed by the low level mlx5 core layer, mlx5 core will
serve as an abstraction layer for trap reporting, since we might have multiple
mlx5 interfaces who might want to report traps on the same device.

Introduce mlx5e_trap which includes a dedicated RQ and NAPI for trapped
packets. Trap-RQ processes packets that were destined to be dropped,
but for debug and visibility sake these packets are trapped and reported
to devlink.
Trap-RQ connects between the HW and the driver and is not a part of a
channel. Open mlx5e_create_rq() and mlx5_core_destroy_rq() as API and
add dedicate RQ handlers which report to devlink of trapped packets.

Change steering flow to optimize traffic in promiscuous mode. On demand,
add a high priority table containing a catch-all rule. All incoming
packets are caught by this rule and steered directly to the TTC table.
Prior to this change, packets in promiscuous mode may suffer from up to
4 steering hops before reaching TTC table.
In addition, this patch will allow us adding a catch-all rule at the end

Early generations of the mv88e6xxx did not have the global 2
registers. In order to keep the driver slim, it was decided to make
the code for these registers optional. Over time, more generations of
switches have been added, always supporting global 2 and adding more
and more registers. No effort has been made to keep these additional
registers also optional to slim the driver down when used for older
generations. Optional global 2 now just gives additional development
and maintenance burden for no real gain.
Make global 2 support always compiled in.

The first two patches are by me and fix typos on the CAN gw protocol and the
flexcan driver.
The next patch is by Vincent Mailhol and targets the CAN driver infrastructure,
it exports the function that converts the CAN state into a human readable
string.
A patch by me, which target the CAN driver infrastructure, too, makes the
calculation in can_fd_len2dlc() more readable.
A patch by Tom Rix fixes a checkpatch warning in the mcba_usb driver.
The next seven patches target the mcp251xfd driver. Su Yanjun's patch replaces
several hardcoded assumptions when calling regmap, by using
regmap_get_val_bytes(). The remaining patches are by me. First an open coded
check is replaced by an existing helper function, then in the TX path the
padding for CAN-FD frames is cleaned up. The next two patches clean up the RTR
frame handling in the RX and TX path. Then support for len8_dlc is added. The
last patch adds BQL support.

Intel Wired LAN Driver Updates 2021-01-26
This series contains updates to the ice, i40e, and igc driver.
Henry corrects setting an unspecified protocol to IPPROTO_NONE instead of
0 for IPv6 flexbytes filters for ice.
Nick fixes the IPv6 extension header being processed incorrectly and
updates the netdev->dev_addr if it exists in hardware as it may have been
modified outside the ice driver.
Brett ensures a user cannot request more channels than available LAN MSI-X
and fixes the minimum allocation logic as it was incorrectly trying to use
more MSI-X than allocated for ice.
Stefan Assmann minimizes the delay between getting and using the VSI
pointer to prevent a possible crash for i40e.
Corinna Vinschen fixes link speed advertising for igc.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
igc: fix link speed advertising
i40e: acquire VSI pointer only after VF is initialized
ice: Fix MSI-X vector fallback logic
ice: Don't allow more channels than LAN MSI-X available
ice: update dev_addr in ice_set_mac_address even if HW filter exists
ice: Implement flow for IPv6 next header (extension header)
ice: fix FDir IPv6 flexbyte

pwm_apply_state() does what the legacy functions pwm_config() and
pwm_{en,dis}able() do in a single function call. This simplifies error
handling and is more efficient for new-style PWM hardware drivers.
Instead of repeatedly querying the PWM framework about the initial PWM
configuration, cache the settings in driver data.
Also use __set_pwm() in .probe() to have the algorithm calculating the PWM
state in a single place.

This patch adds a hwmon driver for the AHT10 Temperature and
Humidity sensor. It has a maximum sample rate, as the datasheet
states that the chip may heat up if it is sampled more than once
every two seconds.
Has been tested a to work on a raspberrypi0w

The pwm-fan driver is extended to support multiple fan tachometer
signals connected to GPIO inputs. This is intended to support the case
where a single PWM output signal is routed to multiple fans, each of
which have a tachometer output connected back to a GPIO pin.
The number of fan tachometer inputs is determined by the number of
interrupt sources configured for the pwm-fan device. The number of
pulses-per-revolution entries should match the number of interrupt
sources so that each input has a value assigned.
The fan tachometer measurements are exposed as sysfs files fan1_input,
fan2_input, etc up to the number of configured inputs.

The data for the (optional) fan tachometer input is moved to a separate
structure which is only allocated if an input is actually configured.
After this change the pulse IRQ handler takes a pointer to the
tachometer data structure instead of the whole device context.

Several power supplies supported by the IBM CFFPS driver don't
report valid data in the CAPABILITY register. This results in PEC
being enabled when it's not supported by the device, and since
the automatic version detection might fail, disable use of the
CAPABILITY register across the board for this driver.

This deletes the ABx500 hwmon driver, the only supported
variant being the AB8500.
This driver has been replaced by generic frameworks. By
inspecting the abx500 sysfs files we see that it contains
things such as temp1_max, temp1_max_alarm, temp1_max_hyst,
temp1_max_hyst_alarm, temp1_min, temp1_min_alarm.
It becomes obvious that the abx500.c is a reimplementation
of thermal zones. This is not very strange as the generic
thermal zones were not invented when this driver was merged
so people were rolling their own.
The ab8500.c driver contains conversion tables for handling
a thermistor on ADC channels AUX1 and AUX2.
I managed to replace the functionality of the driver with:
- Activation of the ntc_thermistor.c driver,
CONFIG_SENSORS_NTC_THERMISTOR
- Activation of thermal zones, CONFIG_THERMAL
- In the device tree, connecting the NTC driver to the
processed IIO channels from the AB8500 GPADC ADC forming
two instances of NTC sensors.
- Connecting the two NTC sensors to a "chassis" thermal zone
in the device tree and setting that to hit the CPU frequency
at 50 degrees celsius and do a critical shutdown at 70
degrees celsius, deploying a policy using the sensors.
After talking to the original authors we concluded that the
driver was never properly parameterized in production so
what we now have in the device tree is already puts the
thermistors to better use than what the hwmon driver did.
The two remaining channels for two battery temperatures is
already handled in the charging algorithms but can be
optionally extended to thermal zones as well if we want
these to trigger critical shutdown for the platform.

====================
net: bridge: multicast: per-port EHT hosts limit
This set adds a simple configurable per-port EHT tracked hosts limit.
Patch 01 adds a default limit of 512 tracked hosts per-port, since the EHT
changes are still only in net-next that shouldn't be a problem. Then
patch 02 adds the ability to configure and retrieve the hosts limit
and to retrieve the current number of tracked hosts per port.
Let's be on the safe side and limit the number of tracked hosts by
default while allowing the user to increase that limit if needed.
