Expose two inline functions that return the offset for a register
whose ID is provided; one of them takes an additional argument
that's used for registers that are parameterized. These both use
a common helper function __ipa_reg_offset(), which just uses the
offset symbols already defined.
Replace all references to the offset macros defined for IPA
registers with calls to ipa_reg_offset() or ipa_reg_n_offset().

Create a new ipa_reg_id enumerated type, which identifies each IPA
register with a symbolic identifier. Use short names, but in some
cases (such as "BCR") add "IPA_" to the name to help avoid name
conflicts.
Create two functions that indicate register validity. The first
concisely indicates whether a register is valid for a given version
of IPA, and if so, whether it is defined. The second indicates
whether a register is valid for TX or RX endpoints.

devlink: fix order of port and netdev register in drivers
Some of the drivers use wrong order in registering devlink port and
netdev, registering netdev first. That was not intended as the devlink
port is some sort of parent for the netdev. Fix the ordering.
Note that the follow-up patchset is going to make this ordering

As sizeof(hwe->data) can now longer be used as the actual size depends
on foe_entry_size, in commit 9d8cb4c096ab02
("net: ethernet: mtk_eth_soc: add foe_entry_size to mtk_eth_soc") the
use of sizeof(hwe->data) is hence replaced.
However, replacing it with ppe->eth->soc->foe_entry_size is wrong as
foe_entry_size represents the size of the whole descriptor and not just
the 'data' field.
Fix this by subtracing the size of the only other field in the struct
'ib1', so we actually end up with the correct size to be copied to the
data field.

net: openvswitch: metering and conntrack in userns
Currently using openvswitch in a non-initial user namespace, e.g., an
unprivileged container, is possible but without metering and conntrack
support. This is due to the restriction of the corresponding Netlink
interfaces to the global CAP_NET_ADMIN.
This simple patches switch from GENL_ADMIN_PERM to GENL_UNS_ADMIN_PERM
in several cases to allow this also for the unprivileged container
use case.
We tested this for unprivileged containers created by the container
manager of GyroidOS (gyroidos.github.io). However, for other container
managers such as LXC or systemd which provide unprivileged containers
this should be apply equally.

This driver seems to have been written under the assumption that messages
can be continued arbitrarily. I'm not when this changed (if ever), but such
ad-hoc continuations are liable to be rudely interrupted. Convert all such
instances to single prints. This loses a bit of timing information (such as
when a line was constructed piecemeal as the function executed), but it's
easy to add a few prints if necessary. This also adds newlines to the ends
of any prints without them.
Since (almost every) debug print included the name of the function, include
it automatically.

Practical experience (and advice from Alexei) tell us that bitfields in
structs lead to un-optimized assembly code. I've verified this change
does lead to better x86_64 assembly, both via objdump and playing with
code snippets in godbolt.org.
Using scripts/bloat-o-meter shows the code size is reduced with 24
bytes for xdp_convert_buff_to_frame() that gets inlined e.g. in
i40e_xmit_xdp_tx_ring() which were used for microbenchmarking.
Microbenchmarking results do show improvements, but very small and
varying between 0.5 to 2 nanosec improvement per packet.
The member @metasize is changed from u8 to u32. Future users of this
area could split this into two u16 fields. I've also benchmarked with
two u16 fields showing equal performance gains and code size reduction.
The moved member @frame_sz doesn't change sizeof struct due to existing
padding. Like xdp_buff member @frame_sz is placed next to @flags, which
allows compiler to optimize assignment of these.

Vladimir Oltean says:
====================
Improve tsn_lib selftests for future distributed tasks
Some of the boards I am working with are limited in the number of ports
that they offer, and as more TSN related selftests are added, it is
important to be able to distribute the work among multiple boards.
A large part of implementing that is ensuring network-wide
synchronization, but also permitting more streams of data to flow
through the network. There is the more important aspect of also
coordinating the timing characteristics of those streams, and that is
also something that is tackled, although not in this modest patch set.
The goal here is not to introduce new selftests yet, but just to lay a
better foundation for them. These patches are a part of the cleanup work
I've done while working on selftests for frame preemption. They are
regression-tested with psfp.sh.

We can make the phc2sys helper not only synchronize a PHC to
CLOCK_REALTIME, which is what it currently does, but also CLOCK_REALTIME
to a PHC, which is going to be needed in distributed TSN tests.
Instead of making the complexity of the arguments passed to
phc2sys_start() explode, we can let it figure out the sync direction
automatically, based on ptp4l's port states.
Towards that goal, pass just the path to the desired ptp4l instance's
UNIX domain socket, and remove the $if_name argument (from which it
derives the PHC). Also adapt the one caller from the ocelot psfp.sh
test. In the case of psfp.sh, phc2sys_start is able to properly figure
out that CLOCK_REALTIME is the source clock and swp1's PHC is the
destination, because of the way in which ptp4l_start for the
UDS_ADDRESS_SWP1 was called: with slave_only=false, so it will always
win the BMCA and always become the sync master between itself and $h1.

Move the PID variable for the isochron receiver into a separate
namespace per stats port, to allow multiple receivers (and/or
orchestration daemons) to be instantiated by the same script.
Preserve the existing behavior by making isochron_do() use the default
stats TCP port of 5000.

Switch ports will want to act as Boundary Clocks, which are configured
using ptp4l by specifying the "-i" argument multiple times.
Since we track a log file and a pid file for each ptp4l instance, and we
want to be compatible with the existing single-port callers of
ptp4l_start and ptp4l_stop, pass the interface list as a single string
of space-separated values. Based on this, we create a label for each
ptp4l instance, where the spaces are replaced with underscores
(ptp4l_start "eth0 eth1" generates "ptp4l_pid_eth0_eth1").

The extra_args argument ($3) of isochron_recv_start is overwritten with
uds ($2), if that argument exists.
This is currently not a problem, because the only TSN selftest
(ocelot/psfp.sh) omits remote sync so it does not specify to the
receiver a UNIX domain socket for ptp4l. So $uds is currently an empty
string.

This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this driver when it is built
as an external module.

SPI devices use the spi_device_id for module autoloading even on
systems using device tree, after commit 5fa6863ba692 ("spi: Check
we have a spi_device_id for each DT compatible"), kernel warns as
follows since the spi_device_id is missing:
SPI driver mse102x has no spi_device_id for vertexcom,mse1021
SPI driver mse102x has no spi_device_id for vertexcom,mse1022
Add spi_device_id entries to silence the warnings, and ensure driver
module autoloading works.

'net-dsa-microchip-ksz9477-enable-interrupt-for-internal-phy-link-detection'
Arun Ramadoss says:
====================
net: dsa: microchip: ksz9477: enable interrupt for internal phy link detection
This patch series implements the common interrupt handling for ksz9477 based
switches and lan937x. The ksz9477 and lan937x has similar interrupt registers
except ksz9477 has 4 port based interrupts whereas lan937x has 6 interrupts.
The patch moves the phy interrupt hanler implemented in lan937x_main.c to
ksz_common.c, along with the mdio_register functionality.

The global port interrupt routines and individual ports interrupt
routines has similar implementation except the mask & status register
and number of nested irqs in them. The mask & status register and
pointer to ksz_device is added to ksz_irq and uses the ksz_irq as
irq_chip_data.
