Donald Hunter says:

====================
tools/net/ynl: Add support for netlink-raw families

This patchset adds support for netlink-raw families such as rtnetlink.

Patch 1 fixes a typo in existing schemas
Patch 2 contains the schema definition
Patches 3 & 4 update the schema documentation
Patches 5 - 9 extends ynl
Patches 10 - 12 add several netlink-raw specs

The netlink-raw schema is very similar to genetlink-legacy and I thought
about making the changes there and symlinking to it. On balance I
thought that might be problematic for accurate schema validation.

rtnetlink doesn't seem to fit into unified or directional message
enumeration models. It seems like an 'explicit' model would be useful,
to force the schema author to specify the message ids directly.

There is not yet support for notifications because ynl currently doesn't
support defining 'event' properties on a 'do' operation. The message ids
are shared so ops need to be both sync and async. I plan to look at this
in a future patch.

The link and route messages contain different nested attributes
dependent on the type of link or route. Decoding these will need some
kind of attr-space selection that uses the value of another attribute as
the selector key. These nested attributes have been left with type
'binary' for now.

75d6d8b5c1 Merge branch 'devlink-mlx5-add-port-function-attributes-for-ipsec'
Saeed Mahameed says:

====================
{devlink,mlx5}: Add port function attributes for ipsec

From Dima:

Introduce hypervisor-level control knobs to set the functionality of PCI
VF devices passed through to guests. The administrator of a hypervisor
host may choose to change the settings of a port function from the
defaults configured by the device firmware.

The software stack has two types of IPsec offload - crypto and packet.
Specifically, the ip xfrm command has sub-commands for "state" and
"policy" that have an "offload" parameter. With ip xfrm state, both
crypto and packet offload types are supported, while ip xfrm policy can
only be offloaded in packet mode.

The series introduces two new boolean attributes of a port function:
ipsec_crypto and ipsec_packet. The goal is to provide a similar level of
granularity for controlling VF IPsec offload capabilities, which would
be aligned with the software model. This will allow users to decide if
they want both types of offload enabled for a VF, just one of them, or
none at all (which is the default).

At a high level, the difference between the two knobs is that with
ipsec_crypto, only XFRM state can be offloaded. Specifically, only the
crypto operation (Encrypt/Decrypt) is offloaded. With ipsec_packet, both
XFRM state and policy can be offloaded. Furthermore, in addition to
crypto operation offload, IPsec encapsulation is also offloaded. For
XFRM state, choosing between crypto and packet offload types is
possible. From the HW perspective, different resources may be required
for each offload type.

Examples of when a user prefers to enable IPsec packet offload for a VF
when using switchdev mode:

  $ devlink port show pci/0000:06:00.0/1
      pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
          function:
          hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet disable

  $ devlink port function set pci/0000:06:00.0/1 ipsec_packet enable

  $ devlink port show pci/0000:06:00.0/1
      pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
          function:
          hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet enable

This enables the corresponding IPsec capability of the function before
it's enumerated, so when the driver reads the capability from the device
firmware, it is enabled. The driver is then able to configure
corresponding features and ops of the VF net device to support IPsec
state and policy offloading.

Implement devlink port function commands to enable / disable IPsec
packet offloads. This is used to control the IPsec capability of the
device.

When ipsec_offload is enabled for a VF, it prevents adding IPsec packet
offloads on the PF, because the two cannot be active simultaneously due
to HW constraints. Conversely, if there are any active IPsec packet
offloads on the PF, it's not allowed to enable ipsec_packet on a VF,
until PF IPsec offloads are cleared.

In the commit 366e46242b ("net/mlx5e: Make IPsec offload work together
with eswitch and TC"), new API to block IPsec vs. TC creation was introduced.

Internally, that API used devlink lock to avoid races with userspace, but it is
not really needed as dev->priv.eswitch is stable and can't be changed. So remove
dependency on devlink lock and move block encap code back to its original place.

====================
Introduce IEP driver and packet timestamping support

This series introduces Industrial Ethernet Peripheral (IEP) driver to
support timestamping of ethernet packets and thus support PTP and PPS
for PRU ICSSG ethernet ports.

This series also adds 10M full duplex support for ICSSG ethernet driver.

There are two IEP instances. IEP0 is used for packet timestamping while IEP1
is used for 10M full duplex support.

This is v7 of the series [v1]. It addresses comments made on [v6].
This series is based on linux-next(#next-20230823).

Changes from v6 to v7:
*) Dropped blank line in example section of patch 1.
*) Patch 1 previously had three examples, removed two examples and kept only
   one example as asked by Krzysztof.
*) Added Jacob Keller's RB tag in patch 5.
*) Dropped Roger's RB tags from the patches that he has authored (Patch 3 and 4)

Changes from v5 to v6:
*) Added description of IEP in commit messages of patch 2 as asked by Rob.
*) Described the items constraints properly for iep property in patch 2 as
   asked by Rob.
*) Added Roger and Simon's RB tags.

Changes from v4 to v5:
*) Added comments on why we are using readl / writel instead of regmap_read()
   / write() in icss_iep_gettime() / settime() APIs as asked by Roger.
*) Added Conor's RB tag in patch 1 and 2.

Change from v3 to v4:
*) Changed compatible in iep dt bindings. Now each SoC has their own compatible
   in the binding with "ti,am654-icss-iep" as a fallback as asked by Conor.
*) Addressed Andew's comments and removed helper APIs icss_iep_readl() /
   writel(). Now the settime/gettime APIs directly use readl() / writel().
*) Moved selecting TI_ICSS_IEP in Kconfig from patch 3 to patch 4.
*) Removed forward declaration of icss_iep_of_match in patch 3.
*) Replaced use of of_device_get_match_data() to device_get_match_data() in
   patch 3.
*) Removed of_match_ptr() from patch 3 as it is not needed.

Changes from v2 to v3:
*) Addressed Roger's comment and moved IEP1 related changes in patch 5.
*) Addressed Roger's comment and moved icss_iep.c / .h changes from patch 4
   to patch 3.
*) Added support for multiple timestamping in patch 4 as asked by Roger.
*) Addressed Andrew's comment and added comment in case SPEED_10 in
   icssg_config_ipg() API.
*) Kept compatible as "ti,am654-icss-iep" for all TI K3 SoCs

Changes from v1 to v2:
*) Addressed Simon's comment to fix reverse xmas tree declaration. Some APIs
   in patch 3 and 4 were not following reverse xmas tree variable declaration.
   Fixed it in this version.
*) Addressed Conor's comments and removed unsupported SoCs from compatible
   comment in patch 1.
*) Addded patch 2 which was not part of v1. Patch 2, adds IEP node to dt
   bindings for ICSSG.

443a2367ba net: ti: icssg-prueth: am65x SR2.0 add 10M full duplex support
For AM65x SR2.0 it's required to enable IEP1 in raw 64bit mode which is
used by PRU FW to monitor the link and apply w/a for 10M link issue.
Note. No public errata available yet.

Without this w/a the PRU FW will stuck if link state changes under TX
traffic pressure.

Hence, add support for 10M full duplex for AM65x SR2.0:
 - add new IEP API to enable IEP, but without PTP support
 - add pdata quirk_10m_link_issue to enable 10M link issue w/a.

186734c158 net: ti: icssg-prueth: add packet timestamping and ptp support
Add packet timestamping TS and PTP PHC clock support.

For AM65x and AM64x:
 - IEP1 is not used
 - IEP0 is configured in shadow mode with 1ms cycle and shared between
Linux and FW. It provides time and TS in number cycles, so special
conversation in ns is required.
 - IEP0 shared between PRUeth ports.
 - IEP0 supports PPS, periodic output.
 - IEP0 settime() and enabling PPS required FW interraction.
 - RX TS provided with each packet in CPPI5 descriptor.
 - TX TS returned through separate ICSSG hw queues for each port. TX TS
readiness is signaled by INTC IRQ. Only one packet at time can be requested
for TX TS.

This set introduces mac source and destination pedit set action offloads.
It also adds offload for ipv4 ttl and ipv6 hop limit pedit set action as
well pedit add actions that would result in the same semantics as
decrementing the ttl and hop limit.

v2:
- fix 'efx_tc_mangle' kdoc which was orphaned when adding 'efx_tc_pedit_add'.
- add description of 'match' in 'efx_tc_mangle' kdoc.
- correct some inconsistent kdoc indentation.
