I've decided to focus just on the MAC Merge layer for now, which is why

v1 (RFC) at:
https://patchwork.kernel.org/project/netdevbpf/cover/20220816222920.1952936-1-vladimir.oltean@nxp.com/

What is being introduced
------------------------

TL;DR: a MAC Merge layer as defined by IEEE 802.3-2018, clause 99
(interspersing of express traffic). This is controlled through ethtool
netlink (ETHTOOL_MSG_MM_GET, ETHTOOL_MSG_MM_SET). The raw ethtool
commands are posted here:
https://patchwork.kernel.org/project/netdevbpf/cover/20230111153638.1454687-1-vladimir.oltean@nxp.com/

The MAC Merge layer has its own statistics counters
(ethtool --include-statistics --show-mm swp0) as well as two member
MACs, the statistics of which can be queried individually, through a new
ethtool netlink attribute, corresponding to:

$ ethtool -I --show-pause eno2 --src aggregate
$ ethtool -S eno2 --groups eth-mac eth-phy eth-ctrl rmon -- --src pmac

The core properties of the MAC Merge layer are described in great detail
in patches 02/12 and 03/12. They can be viewed in "make htmldocs" format.

Devices for which the API is supported
--------------------------------------

I decided to start with the Ethernet switch on NXP LS1028A (Felix)
because of the smaller patch set. I also have support for the ENETC
controller pending.

I would like to get confirmation that the UAPI being proposed here will
not restrict any use cases known by other hardware vendors.

Why is support for preemptible traffic classes not here?
--------------------------------------------------------

There is legitimate concern whether the 802.1Q portion of the standard
(which traffic classes go to the eMAC and which to the pMAC) should be
modeled in Linux using tc or using another UAPI. I think that is
stalling the entire series, but should be discussed separately instead.
Removing FP adminStatus support makes me confident enough to submit this
patch set without an RFC tag (meaning: I wouldn't mind if it was merged
as is).

What is submitted here is sufficient for an LLDP daemon to do its job.
I've patched openlldp to advertise and configure frame preemption:
https://github.com/vladimiroltean/openlldp/tree/frame-preemption-v3

In case someone wants to try it out, here are some commands I've used.

# Configure the interfaces to receive and transmit LLDP Data Units
lldptool -L -i eno0 adminStatus=rxtx
lldptool -L -i swp0 adminStatus=rxtx
# Enable the transmission of certain TLVs on switch's interface
lldptool -T -i eno0 -V addEthCap enableTx=yes
lldptool -T -i swp0 -V addEthCap enableTx=yes
# Query LLDP statistics on switch's interface
lldptool -S -i swp0
# Query the received neighbor TLVs
lldptool -i swp0 -t -n -V addEthCap
Additional Ethernet Capabilities TLV
Preemption capability supported
Preemption capability enabled
Preemption capability active
Additional fragment size: 60 octets

So using this patch set, lldpad will be able to advertise and configure
frame preemption, but still, no data packet will be sent as preemptible
over the link, because there is no UAPI to control which traffic classes
are sent as preemptible and which as express.

Preemptable or preemptible?
---------------------------

IEEE 802.3 uses "preemptable" throughout. IEEE 802.1Q uses "preemptible"
throughout. Because the definition of "preemptible" falls under 802.1Q's
jurisdiction and 802.3 just references it, I went with the 802.1Q naming
even where supporting an 802.3 feature. Also, checkpatch agrees with this.

net: ethtool: add support for MAC Merge layer

clause 6.7.2), which w

net: ethtool: add support for MAC Merge layer

The MAC merge sublayer (IEEE 802.3-2018 clause 99) is one of 2
specifications (the other being Frame Preemption; IEEE 802.1Q-2018
clause 6.7.2), which work together to minimize latency caused by frame
interference at TX. The overall goal of TSN is for normal traffic and
traffic with a bounded deadline to be able to cohabitate on the same L2
network and not bother each other too much.

The standards achieve this (partly) by introducing the concept of
preemptible traffic, i.e. Ethernet frames that have a custom value for
the Start-of-Frame-Delimiter (SFD), and these frames can be fragmented
and reassembled at L2 on a link-local basis. The non-preemptible frames
are called express traffic, they are transmitted using a normal SFD, and
they can preempt preemptible frames, therefore having lower latency,
which can matter at lower (100 Mbps) link speeds, or at high MTUs (jumbo
frames around 9K). Preemption is not recursive, i.e. a P frame cannot
preempt another P frame. Preemption also does not depend upon priority,
or otherwise said, an E frame with prio 0 will still preempt a P frame
with prio 7.

In terms of implementation, the standards talk about the presence of an
express MAC (eMAC) which handles express traffic, and a preemptible MAC
(pMAC) which handles preemptible traffic, and these MACs are multiplexed
on the same MII by a MAC merge layer.

To support frame preemption, the definition of the SFD was generalized
to SMD (Start-of-mPacket-Delimiter), where an mPacket is essentially an
Ethernet frame fragment, or a complete frame. Stations unaware of an SMD
value different from the standard SFD will treat P frames as error
frames. To prevent that from happening, a negotiation process is
defined.

On RX, packets are dispatched to the eMAC or pMAC after being filtered
by their SMD. On TX, the eMAC/pMAC classification decision is taken by
the 802.1Q spec, based on packet priority (each of the 8 user priority
values may have an admin-status of preemptible or express).

The MAC Merge layer and the Frame Preemption parameters have some degree
of independence in terms of how software stacks are supposed to deal
with them. The activation of the MM layer is supposed to be controlled
by an LLDP daemon (after it has been communicated that the link partner
also supports it), after which a (hardware-based or not) verification
handshake takes place, before actually enabling the feature. So the
process is intended to be relatively plug-and-play. Whereas FP settings
are supposed to be coordinated across a network using something
approximating NETCONF.

The support contained here is exclusively for the 802.3 (MAC Merge)
portions and not for the 802.1Q (Frame Preemption) parts. This API is
sufficient for an LLDP daemon to do its job. The FP adminStatus variable
from 802.1Q is outside the scope of an LLDP daemon.

I have taken a few creative licenses and augmented the Linux kernel UAPI
compared to the standard managed objects recommended by IEEE 802.3.
These are:

- ETHTOOL_A_MM_PMAC_ENABLED: According to Figure 99-6: Receive
Processing state diagram, a MAC Merge layer is always supposed to be
able to receive P frames. However, this implies keeping the pMAC
powered on, which will consume needless power in applications where FP
will never be used. If LLDP is used, the reception of an Additional
Ethernet Capabilities TLV from the link partner is sufficient
indication that the pMAC should be enabled. So my proposal is that in
Linux, we keep the pMAC turned off by default and that user space
turns it on when needed.

- ETHTOOL_A_MM_VERIFY_ENABLED: The IEEE managed object is called
aMACMergeVerifyDisableTx. I opted for consistency (positive logic) in
the boolean netlink attributes offered, so this is also positive here.
Other than the meaning being reversed, they correspond to the same
thing.

- ETHTOOL_A_MM_MAX_VERIFY_TIME: I found it most reasonable for a LLDP
daemon to maximize the verifyTime variable (delay between SMD-V
transmissions), to maximize its chances that the LP replies. IEEE says
that the verifyTime can range between 1 and 128 ms, but the NXP ENETC
stupidly keeps this variable in a 7 bit register, so the maximum
supported value is 127 ms. I could have chosen to hardcode this in the
LLDP daemon to a lower value, but why not let the kernel expose its
supported range directly.

- ETHTOOL_A_MM_TX_MIN_FRAG_SIZE: the standard managed object is called
aMACMergeAddFragSize, and expresses the "additional" fragment size
(on top of ETH_ZLEN), whereas this expresses the absolute value of the
fragment size.

- ETHTOOL_A_MM_RX_MIN_FRAG_SIZE: there doesn't appear to exist a managed
object mandated by the standard, but user space clearly needs to know
what is the minimum supported fragment size of our local receiver,
since LLDP must advertise a value no lower than that.

Merge branch 'NCN26000-PLCA-RS-support'

Piergiorgio Beruto says:

====================
net: add PLCA RS support and onsemi NCN26000

This patchset adds support for getting/setting the Physical Layer
Collision Avoidace (PLCA) Reconciliation Sublayer (RS) configuration and
status on Ethernet PHYs that supports it.

PLCA is a feature that provides improved media-access performance in terms
of throughput, latency and fairness for multi-drop (P2MP) half-duplex PHYs.
PLCA is defined in Clause 148 of the IEEE802.3 specifications as amended
by 802.3cg-2019. Currently, PLCA is supported by the 10BASE-T1S single-pair
Ethernet PHY defined in the same standard and related amendments. The OPEN
Alliance SIG TC14 defines additional specifications for the 10BASE-T1S PHY,
including a standard register map for PHYs that embeds the PLCA RS (see
PLCA management registers at https://www.opensig.org/about/specifications/).

The changes proposed herein add the appropriate ethtool netlink interface
for configuring the PLCA RS on PHYs that supports it. A separate patchset
further modifies the ethtool userspace program to show and modify the
configuration/status of the PLCA RS.

Additionally, this patchset adds support for the onsemi NCN26000
Industrial Ethernet 10BASE-T1S PHY that uses the newly added PLCA
infrastructure.

communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).

- Allow targeting BPF iterators to loop through resources of one
task/thread.

- Add ability to call selected destructive functions. Expose
crash_kexec() to allow BPF to trigger a kernel dump. Use
CAP_SYS_BOOT check on the loading process to judge permissions.

- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.

- Support struct arguments for trampoline based programs. Only
structs with size <= 16B and x86 are supported.

- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).

- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.

- Support accessing network tunnel metadata's flags.

- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.

- Add support for writing to Netfilter's nf_conn:mark.

Protocols:

- WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
(MLO) work (802.11be, WiFi 7).

- vsock: improve support for SO_RCVLOWAT.

- SMC: support SO_REUSEPORT.

- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.

- IPSec: support collect metadata mode for xfrm interfaces.

- TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
packets.

- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).

- MPTCP: support TCP_FASTOPEN_CONNECT.

- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.

- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.

- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.

- TLS: support the Korean ARIA-GCM crypto algorithm.

- Remove DECnet support.

Driver API:

- Allow selecting the conduit interface used by each port in DSA
switches, at runtime.

- Ethernet Power Sourcing Equipment and Power Device support.

- Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
traffic class max frame size for time-based packet schedules.

- Support PHY rate matching - adapting between differing host-side
and link-side speeds.

- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.

- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.

- Require that flash component name used during update matches one of
the components for which version is reported by info_get().

- Remove "weight" argument from driver-facing NAPI API as much as
possible. It's one of those magic knobs which seemed like a good
idea at the time but is too indirect to use in practice.

- Support offload of TLS connections with 256 bit keys.

ethtool: add interface to interact with Ethernet Power Equipment

Add interface to support Power Sourcing Equipment. At current step it
provides generic way to address all variants of PSE devices as defined
in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4
PoDL Power Sourcing Equipment (PSE).

Currently supported and mandatory objects are:
IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus
IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState
IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl

This is minimal interface needed to control PSE on each separate
ethernet port but it provides not all mandatory objects specified in
IEEE 802.3-2018.

Since "PoDL PSE" and "PSE" have similar names, but some different values
I decide to not merge them and keep separate naming schema. This should
allow as to be as close to IEEE 802.3 spec as possible and avoid name
conflicts in the future.

This implementation is connected to PHYs instead of MACs because PSE
auto classification can potentially interfere with PHY auto negotiation.
So, may be some extra PHY related initialization will be needed.

With WIP version of ethtools interaction with PSE capable link looks
as following:

$ ip l
...
5: t1l1@eth0: <BROADCAST,MULTICAST> ..
...

$ ethtool --show-pse t1l1
PSE attributs for t1l1:
PoDL PSE Admin State: disabled
PoDL PSE Power Detection Status: disabled

$ ethtool --set-pse t1l1 podl-pse-admin-control enable
$ ethtool --show-pse t1l1
PSE attributs for t1l1:
PoDL PSE Admin State: enabled
PoDL PSE Power Detection Status: delivering power
