net: introduce struct ubuf_info_msgzc
We're going to split struct ubuf_info and leave there only
mandatory fields. Users are free to extend it. Add struct
ubuf_info_msgzc, which will be an extended version for MSG_ZEROCOPY and
some other users. It duplicates of struct ubuf_info for now and will be
removed in a couple of patches.

sfc: bare bones TC offload
This series begins the work of supporting TC flower offload on EF100 NICs.
This is the absolute minimum viable TC implementation to get traffic to
VFs and allow them to be tested; it supports no match fields besides
ingress port, no actions besides mirred and drop, and no stats.
More matches, actions, and counters will be added in subsequent patches.

Alex Elder says:
====================
net: ipa: generalized register definitions
This series is quite a bit bigger than what I normally like to send,
and I apologize for that. I would like it to get incorporated in
its entirety this week if possible, and splitting up the series
carries a small risk that wouldn't happen.
Each IPA register has a defined offset, and in most cases, a set
of masks that define the width and position of fields within the
register. Most registers currently use the same offset for all
versions of IPA. Usually fields within registers are also the same
across many versions. Offsets and fields like this are defined
using preprocessor constants.
When a register has a different offset for different versions of
IPA, an inline function is used to determine its offset. And in
places where a field differs between versions, an inline function is
used to determine how a value is encoded within the field, depending
on IPA version.
Starting with IPA version 5.0, the number of IPA endpoints supported
is greater than 32. As a consequence, *many* IPA register offsets
differ considerably from prior versions. This increase in endpoints
also requires a lot of field sizes and/or positions to change (such
as those that contain an endpoint ID).
Defining these things with constants is no longer simple, and rather
than fill the code with one-off functions to define offsets and
encode field values, this series puts in place a new way of defining
IPA registers and their fields. Note that this series creates this
new scheme, but does not add IPA v5.0+ support.
An enumerated type will now define a unique ID for each IPA register.
Each defined register will have a structure that contains its offset
and its name (a printable string). Each version of IPA will have an
array of these register structures, indexed by register ID.
Some "parameterized" registers are duplicated (this is not new).
For example, each endpoint has an INIT_HDR register, and the offset
of a given endpoint's INIT_HDR register is dependent on the endpoint
number (the parameter). In such cases, the register's "stride" is
defined as the distance between two of these registers.
If a register contains fields, each field will have a unique ID
that's used as an index into an array of field masks defined for the
register. The register structure also defines the number of entries
in this field array.
When a register is to be used in code, its register structure will
be fetched using function ipa_reg(). Other functions are then used
to determine the register's offset, or to encode a value into one of
the register's fields, and so on.
Each version of IPA defines the set of registers that are available,
including all fields for these registers. The array of defined
registers is set up at probe time based on the IPA version, and it
is associated with the main IPA structure.

net: ipa: introduce ipa_reg field masks
Add register field descriptors to the ipa_reg structure. A field in
a register is defined by a field mask, which is a 32-bit mask having
a single contiguous range of bits set.
For each register that has at least one field defined, an enumerated
type will identify the register's fields. The ipa_reg structure for
that register will include an array fmask[] of field masks, indexed
by that enumerated type. Each field mask defines the position and
bit width of a field. An additional "fcount" records how many
fields (masks) are defined for a given register.
Introduce two macros to be used to define registers that have at
least one field.
Introduce a few new functions related to field masks. The first
simply returns a field mask, given an IPA register pointer and field
mask ID. A variant of that is meant to be used for the special case
of single-bit field masks.
Next, ipa_reg_encode(), identifies a field with an IPA register
pointer and a field ID, and takes a value to represent in that
field. The result encodes the value in the appropriate place to be
stored in the register. This is roughly modeled after the bitmask
operations (like u32_encode_bits()).
Another function (ipa_reg_decode()) similarly identifies a register
field, but the value supplied to it represents a full register
value. The value encoded in the field is extracted from the value
and returned. This is also roughly modeled after bitmask operations
(such as u32_get_bits()).
Finally, ipa_reg_field_max() returns the maximum value representable
by a field.

NFC: hci: Split memcpy() of struct hcp_message flexible array
To work around a misbehavior of the compiler's ability to see into
composite flexible array structs (as detailed in the coming memcpy()
hardening series[1]), split the memcpy() of the header and the payload
so no false positive run-time overflow warning will be generated. This

net: ethernet: mtk_eth_soc: fix usage of foe_entry_size
As sizeof(hwe->data) can now longer be used as the actual size depends

("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

Currently using openvswitch in a non-initial user namespace, e.g., an

This simple patches switch from GENL_ADMIN_PERM to GENL_UNS_ADMIN_PERM

We tested this for unprivileged containers created by the container

this should be apply equally.

xdp: Adjust xdp_frame layout to avoid using bitfields
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.

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

We can make the phc2sys helper not only synchronize a PHC to
CLOCK_REALTIME, which is what it currently does, but also CLOCK_REALTIME

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

win the BMCA and always become the sync master between itself and $h1.

selftests: net: tsn_lib: allow running ptp4l on multiple interfaces
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").

selftests: net: tsn_lib: don't overwrite isochron receiver extra args with UDS
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.

====================
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.
