This adds a driver core for the Realtek SMI chips and a
subdriver for the RTL8366RB. I just added this chip simply
because it is all I can test.
The code is a massaged variant of the code that has been
sitting out-of-tree in OpenWRT for years in the absence of
a proper switch subsystem. This creates a DSA driver for it.
I have tried to credit the original authors wherever
possible.
The main changes I've done from the OpenWRT code:
- Added an IRQ chip inside the RTL8366RB switch to demux and
handle the line state IRQs.
- Distributed the phy handling out to the PHY driver.
- Added some RTL8366RB code that was missing in the driver at
the time, such as setting up "green ethernet" with a funny
jam table and forcing MAC5 (the CPU port) into 1 GBit.
- Select jam table and add the default jam table from the
vendor driver, also for ASIC "version 0" if need be.
- Do not store jam tables in the device tree, store them
in the driver.
- Pick in the "initvals" jam tables from OpenWRT's driver
and make those get selected per compatible for the
whole system. It's apparently about electrical settings
for this system and whatnot, not really configuration
from device tree.
- Implemented LED control: beware of bugs because there are
no LEDs on the device I am using!
We do not implement custom DSA tags. This is explained in
a comment in the driver as well: this "tagging protocol" is
not simply a few extra bytes tagged on to the ethernet
frame as DSA is used to. Instead, enabling the CPU tags
will make the switch start talking Realtek RRCP internally.
For example a simple ping will make this kind of packets
appear inside the switch:
As you can see a custom "8899" tagged packet using the
protocol 0xa2. Norm RRCP appears to always have this
protocol set to 0x01 according to OpenRRCP. You can also
see that this is not a ping packet at all, instead the
switch is starting to talk network management issues
with the CPU port.
So for now custom "tagging" is disabled.
This was tested on the D-Link DIR-685 with initramfs and
OpenWRT userspaces and works fine on all the LAN ports
(lan0 .. lan3). The WAN port is yet not working.

The Realtek SMI family is a set of DSA chips that provide
switching in routers. This binding just follows the pattern
set by other switches but with the introduction of an embedded
irqchip to demux and handle the interrupts fired by the single
line from the chip.
This interrupt construction is similar to how we handle
interrupt controllers inside PCI bridges etc.

PHY driver core pick up the IRQ from the switch chip.

The removed code would be called in two situations:

leaving probe(). open() callback will power up the chip.
In case 2 we call rtl_pll_power_down() twice currently, from the
close() callback and 10s later when entering runtime-suspend.

HWMON support for SFP modules
This patchset adds HWMON support to SFP modules. The two patches add
some attributes for temperature and power sensors which are currently
missing from the hwmon core. The third patch adds a helper for
filtering out characters in hwmon names which are invalid. The last
patch then extends the core SFP code to export the sensors found in
SFP modules.
This code has been tested with two SFP modules:
module OEM SFP-7000-85 rev 11.0 sn M1512220075 dc 160221
module FINISAR CORP. FTLF8524E2GNL rev A sn PW40MNN dc 160725
The anonymous module uses external calibration, while the FINISAR uses
internal calibration. Thus both code paths have been tested.

Miller will merge them all via net-next.

net: phy: sfp: Add HWMON support for module sensors
SFP modules can contain a number of sensors. The EEPROM also contains
recommended alarm and critical values for each sensor, and indications
of if these have been exceeded. Export this information via
HWMON. Currently temperature, VCC, bias current, transmit power, and
possibly receiver power is supported.
The sensors in the modules can either return calibrate or uncalibrated
values. Uncalibrated values need to be manipulated, using coefficients
provided in the SFP EEPROM. Uncalibrated receive power values require
floating point maths in order to calibrate them. Performing this in
the kernel is hard. So if the SFP module indicates it uses
uncalibrated values, RX power is not made available.
With this hwmon device, it is possible to view the sensor values using
lm-sensors programs:
in0: +3.29 V (crit min = +2.90 V, min = +3.00 V)
(max = +3.60 V, crit max = +3.70 V)
temp1: +33.0°C (low = -5.0°C, high = +80.0°C)
(crit low = -10.0°C, crit = +85.0°C)
power1: 1000.00 nW (max = 794.00 uW, min = 50.00 uW) ALARM (LCRIT)
(lcrit = 40.00 uW, crit = 1000.00 uW)
curr1: +0.00 A (crit min = +0.00 A, min = +0.00 A) ALARM (LCRIT, MIN)
(max = +0.01 A, crit max = +0.01 A)
The scaling sensors performs on the bias current is not particularly
good. The raw values are more useful:
In order to keep the I2C overhead to a minimum, the constant values,
such as limits and calibration coefficients are read once at module
insertion time. Thus only reading *_input and *_alarm properties
requires i2c read operations.

The following series provides TLS RX inline crypto offload.

v4->v3:
- Remove the iov revert for zero copy send flow
v2->v3:
- Fix typo
- Adjust cover letter
- Fix bug in zero copy flows
- Use network byte order for the record number in resync
- Adjust the sequence provided in resync
v1->v2:
- Fix bisectability problems due to variable name changes
- Fix potential uninitialized return value
This series completes the generic infrastructure to offload TLS crypto to
a network devices. It enables the kernel TLS socket to skip decryption and
authentication operations for SKBs marked as decrypted on the receive
side of the data path. Leaving those computationally expensive operations
to the NIC.
This infrastructure doesn't require a TCP offload engine. Instead, the
NIC decrypts a packet's payload if the packet contains the expected TCP
sequence number. The TLS record authentication tag remains unmodified
regardless of decryption. If the packet is decrypted successfully and it
contains an authentication tag, then the authentication check has passed.
Otherwise, if the authentication fails, then the packet is provided
unmodified and the KTLS layer is responsible for handling it.
Out-Of-Order TCP packets are provided unmodified. As a result,
in the slow path some of the SKBs are decrypted while others remain as
ciphertext.
The GRO and TCP layers must not coalesce decrypted and non-decrypted SKBs.
At the worst case a received TLS record consists of both plaintext
and ciphertext packets. These partially decrypted records must be
reencrypted, only to be decrypted.
The notable differences between SW KTLS and NIC offloaded TLS
implementations are as follows:
1. Partial decryption - Software must handle the case of a TLS record
that was only partially decrypted by HW. This can happen due to packet
reordering.
2. Resynchronization - tls_read_size calls the device driver to
resynchronize HW whenever it lost track of the TLS record framing in
the TCP stream.
The infrastructure should be extendable to support various NIC offload
implementations. However it is currently written with the
implementation below in mind:
The NIC identifies packets that should be offloaded according to
the 5-tuple and the TCP sequence number. If these match and the
packet is decrypted and authenticated successfully, then a syndrome
is provided to software. Otherwise, the packet is unmodified.
Decrypted and non-decrypted packets aren't coalesced by the network stack,
and the KTLS layer decrypts and authenticates partially decrypted records.
The NIC provides an indication whenever a resync is required. The resync
operation is triggered by the KTLS layer while parsing TLS record headers.
Finally, we measure the performance obtained by running single stream
iperf with two Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz machines connected
back-to-back with Innova TLS (40Gbps) NICs. We compare TCP (upper bound)
and KTLS-Offload running both in Tx and Rx. The results show that the
performance of offload is comparable to TCP.

having easy access to some of the many lookup tables configuration is
helpful during development and debug.
This series adds a basic debugfs interface, allowing to read data from
the Header Parser and some of the Classifier tables.
For now, the interface is read-only, and contains only some basic info.
This was actually used during RSS development, and might be useful to
troubleshoot some issues we might find.
The first patch of the series converts the mvpp2 files to SPDX, which

The classification operations that are used for RSS make use of several
lookup tables. Having hit counters for these tables is really helpful
to determine what flows were matched by ingress traffic, and see the
path of packets among all the classifier tables.
This commit adds hit counters for the 3 tables used at the moment :
- The decoding table (also called lookup_id table), that links flows
identified by the Header Parser to the flow table.
There's one entry per flow, located at :
.../mvpp2/<controller>/flows/XX/dec_hits
Note that there are 21 flows in the decoding table, whereas there are
52 flows in the Header Parser. That's because there are several kind
of traffic that will match a given flow. Reading the hit counter from
one sub-flow will clear all hit counter that have the same flow_id.
This also applies to the flow_hits.
- The flow table, that contains all the different lookups to be
performed by the classifier for each packet of a given flow. The match
is done on the first entry of the flow sequence.
- The C2 engine entries, that are used to assign the default rx queue,
and enable or disable RSS for a given port.
There's one entry per flow, located at:
.../mvpp2/<controller>/flows/XX/flow_hits
There is one C2 entry per port, so the c2 hit counter is located at :
.../mvpp2/<controller>/ethX/c2_hits
All hit counter values are 16-bits clear-on-read values.

net: mvpp2: debugfs: add entries for classifier flows
The classifier configuration for RSS is quite complex, with several
lookup tables being used. This commit adds useful info in debugfs to
see how the different tables are configured :
Added 2 new entries in the per-port directory :
- .../eth0/default_rxq : The default rx queue on that port
- .../eth0/rss_enable : Indicates if RSS is enabled in the C2 entry
Added the 'flows' directory :
It contains one entry per sub-flow. a 'sub-flow' is a unique path from
Header Parser to the flow table. Multiple sub-flows can point to the
same 'flow' (each flow has an id from 8 to 29, which is its index in the
Lookup Id table) :
- .../flows/00/...
/01/...
...
/51/id : The flow id. There are 21 unique flows. There's one
flow per combination of the following parameters :
- L4 protocol (TCP, UDP, none)
- L3 protocol (IPv4, IPv6)
- L3 parameters (Fragmented or not)
- L2 parameters (Vlan tag presence or not)
.../type : The flow type. This is an even higher level flow,
that we manipulate with ethtool. It can be :
"udp4" "tcp4" "udp6" "tcp6" "ipv4" "ipv6" "other".
.../eth0/...
.../eth1/engine : The hash generation engine used for this
flow on the given port
.../hash_opts : The hash generation options indicating on
what data we base the hash (vlan tag, src

callback can be called on future state transition, and when such a

verify it in user space later.
Reduce amount of copy/paste for debug info when result is verified in
the test and keep that info together with values being checked so that
they won't get out of sync.
It also improves debug experience: instead of checking manually what
