The driver core first registers with the hwmon and thermal subsystems
and only then proceeds to initialize the switch driver (e.g.,
mlxsw_spectrum). It is only during the last stage that the current
firmware version is validated and a newer one flashed, if necessary.

The above means that if a new firmware feature is utilized by the
hwmon/thermal code, the driver will not be able to load.

Solve this by re-ordering initializing the switch driver before
registering with the hwmon and thermal subsystems.

Current implementation uses fixed size of I2C data transaction buffer.
Allow to set size of I2C transactions according to I2C physical adapter
capability. For that purpose adapter read and write size is obtained
from the I2C physical adapter and buffer size is set according to the
minimum of these two values. If adapter does not provide such info,
default buffer size is to be used.
It allows to improve performance of I2C access to silicon when long

The smp_store_release call in fqdir_exit cannot protect the setting
of fqdir->dead as claimed because its memory barrier is only
guaranteed to be one-way and the barrier precedes the setting of
fqdir->dead.

IOW it doesn't provide any barriers between fq->dir and the following
hash table destruction.

In fact, the code is safe anyway because call_rcu does provide both
the memory barrier as well as a guarantee that when the destruction
work starts executing all RCU readers will see the updated value for
fqdir->dead.

Therefore this patch removes the unnecessary smp_store_release call
as well as the corresponding READ_ONCE on the read-side in order to
not confuse future readers of this code.  Comments have been added
in their places.

Decoupling PHYLINK from struct net_device

Following two separate discussion threads in:
  https://www.spinics.net/lists/netdev/msg569087.html
and:
  https://www.spinics.net/lists/netdev/msg570450.html

Previous RFC patch set: https://www.spinics.net/lists/netdev/msg571995.html

PHYLINK was reworked in order to accept multiple operation types,
PHYLINK_NETDEV and PHYLINK_DEV, passed through a phylink_config
structure alongside the corresponding struct device.

One of the main concerns expressed in the RFC was that using notifiers
to signal the corresponding phylink_mac_ops would break PHYLINK's API
unity and that it would become harder to grep for its users.
Using the current approach, we maintain a common API for all users.
Also, printing useful information in PHYLINK, when decoupled from a
net_device, is achieved using dev_err&co on the struct device received
(in DSA's case is the device corresponding to the dsa_switch).

PHYLIB (which PHYLINK uses) was reworked to the extent that it does not
crash when connecting to a PHY and the net_device pointer is NULL.

Lastly, DSA has been reworked in its way that it handles PHYs for ports
that lack a net_device (CPU and DSA ports).  For these, it was
previously using PHYLIB and is now using the PHYLINK_DEV operation type.
Previously, a driver that wanted to support PHY operations on CPU/DSA
ports has to implement .adjust_link(). This patch set not only gives
drivers the options to use PHYLINK uniformly but also urges them to
convert to it. For compatibility, the old code is kept but it will be
removed once all drivers switch over.

The patchset was tested on the NXP LS1021A-TSN board having the
following Ethernet layout:
  https://lkml.org/lkml/2019/5/5/279
The CPU port was moved from the internal RGMII fixed-link (enet2 ->
switch port 4) to an external loopback Cat5 cable between the enet1 port
and the front-facing swp2 SJA1105 port. In this mode, both the master
and the CPU port have an attached PHY which detects link change events:

[   49.105426] fsl-gianfar soc:ethernet@2d50000 eth1: Link is Down
[   50.305486] sja1105 spi0.1: Link is Down
[   53.265596] fsl-gianfar soc:ethernet@2d50000 eth1: Link is Up - 1Gbps/Full - flow control off
[   54.466304] sja1105 spi0.1: Link is Up - 1Gbps/Full - flow control off

Changes in v2:
  - fixed sparse warnings
  - updated 'Documentation/ABI/testing/sysfs-class-net-phydev'
====================

PHYLIB and PHYLINK handle fixed-link interfaces differently. PHYLIB
wraps them in a software PHY ("pseudo fixed link") phydev construct such
that .adjust_link driver callbacks see an unified API. Whereas PHYLINK
simply creates a phylink_link_state structure and passes it to
.mac_config.

At the time the driver was introduced, DSA was using PHYLIB for the
CPU/cascade ports (the ones with no net devices) and PHYLINK for
everything else.

As explained below:

commit aab9c406
Author: Florian Fainelli <f.fainelli@gmail.com>
Date:   Thu May 10 13:17:36 2018 -0700

  net: dsa: Plug in PHYLINK support

  Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2)
  will need to implement phylink_mac_ops from now on to preserve
  functionality, since PHYLINK *does not* create a phy_device instance
  for fixed links.

In the above patch, DSA guards the .phylink_mac_config callback against
a NULL phydev pointer.  Therefore, .adjust_link is not called in case of
a fixed-link user port.

This patch fixes the situation by converting the driver from using
.adjust_link to .phylink_mac_config.  This can be done now in a unified
fashion for both slave and CPU/cascade ports because DSA now uses
PHYLINK for all ports.

For DSA switches that do not have an .adjust_link callback, aka those
who transitioned totally to the PHYLINK-compliant API, use PHYLINK to
drive the CPU/DSA ports.

The PHYLIB usage and .adjust_link are kept but deprecated, and users are
asked to transition from it.  The reason why we can't do anything for
them is because PHYLINK does not wrap the fixed-link state behind a
phydev object, so we cannot wrap .phylink_mac_config into .adjust_link
unless we fabricate a phy_device structure.

For these ports, the newly introduced PHYLINK_DEV operation type is
used and the dsa_switch device structure is passed to PHYLINK for
printing purposes.  The handling of the PHYLINK_NETDEV and PHYLINK_DEV
PHYLINK instances is common from the perspective of the driver.

Also, netif_carrier_* calls ar guarded by the presence of a valid

The phylink_config structure will encapsulate a pointer to a struct
device and the operation type requested for this instance of PHYLINK.
This patch does not make any functional changes, it just transitions the
PHYLINK internals and all its users to the new API.

A pointer to a phylink_config structure will be passed to
phylink_create() instead of the net_device directly. Also, the same
phylink_config pointer will be passed back to all phylink_mac_ops
callbacks instead of the net_device. Using this mechanism, a PHYLINK
user can get the original net_device using a structure such as
'to_net_dev(config->dev)' or directly the structure containing the
phylink_config using a container_of call.

At the moment, only the PHYLINK_NETDEV is defined as a valid operation
type for PHYLINK. In this mode, a valid reference to a struct device
linked to the original net_device should be passed to PHYLINK through
the phylink_config structure.

This API changes is mainly driven by the necessity of adding a new
operation type in PHYLINK that disconnects the phy_device from the
net_device and also works when the net_device is lacking.

ctinfo is a new tc filter action module.  It is designed to restore
information contained in firewall conntrack marks to other packet fields
and is typically used on packet ingress paths.  At present it has two
independent sub-functions or operating modes, DSCP restoration mode &
skb mark restoration mode.

The DSCP restore mode:

This mode copies DSCP values that have been placed in the firewall
conntrack mark back into the IPv4/v6 diffserv fields of relevant
packets.

The DSCP restoration is intended for use and has been found useful for
restoring ingress classifications based on egress classifications across
links that bleach or otherwise change DSCP, typically home ISP Internet
links.  Restoring DSCP on ingress on the WAN link allows qdiscs such as
but by no means limited to CAKE to shape inbound packets according to
policies that are easier to set & mark on egress.

Ingress classification is traditionally a challenging task since
iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
lookups, hence are unable to see internal IPv4 addresses as used on the
typical home masquerading gateway.  Thus marking the connection in some
manner on egress for later restoration of classification on ingress is
easier to implement.

Parameters related to DSCP restore mode:

dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the
conntrack mark field contain the DSCP value to be restored.

statemask - a 32 bit mask of (usually) 1 bit length, outside the area
specified by dscpmask.  This represents a conditional operation flag
whereby the DSCP is only restored if the flag is set.  This is useful to
implement a 'one shot' iptables based classification where the
'complicated' iptables rules are only run once to classify the
connection on initial (egress) packet and subsequent packets are all
marked/restored with the same DSCP.  A mask of zero disables the
conditional behaviour ie. the conntrack mark DSCP bits are always
restored to the ip diffserv field (assuming the conntrack entry is found
& the skb is an ipv4/ipv6 type)

e.g. dscpmask 0xfc000000 statemask 0x01000000

|----0xFC----conntrack mark----000000---|
| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
| DSCP       | unused | flag  |unused   |

      |                   |
      |                   |
      ---|             Conditional flag
         v             only restore if set
|-ip diffserv-|
| 6 bits      |
|-------------|

The skb mark restore mode (cpmark):

This mode copies the firewall conntrack mark to the skb's mark field.
It is completely the functional equivalent of the existing act_connmark
action with the additional feature of being able to apply a mask to the
restored value.

Parameters related to skb mark restore mode:

mask - a 32 bit mask applied to the firewall conntrack mark to mask out
bits unwanted for restoration.  This can be useful where the conntrack
mark is being used for different purposes by different applications.  If
not specified and by default the whole mark field is copied (i.e.
default mask of 0xffffffff)

e.g. mask 0x00ffffff to mask out the top 8 bits being used by the
aforementioned DSCP restore mode.

|----0x00----conntrack mark----ffffff---|
| Bits 31-24 |                          |
| DSCP & flag|      some value here     |

Hardware offload of matchall classifier and police action are now
supported via the tc command.
Supported police parameters are: rate and burst.

Example:

Add:
tc qdisc add dev eth3 handle ffff: ingress
tc filter add dev eth3 parent ffff: prio 1 handle 2	\
	matchall skip_sw				\
	action police rate 100Mbit burst 10000

Show:
tc -s -d qdisc show dev eth3
tc -s -d filter show dev eth3 ingress

Delete:
tc filter del dev eth3 parent ffff: prio 1
tc qdisc del dev eth3 handle ffff: ingress

100GbE Intel Wired LAN Driver Updates 2019-05-29

This series contains updates to ice driver only.

Bruce cleans up white space issues and fixes complaints about using
bitop assignments using operands of different sizes.

Anirudh cleans up code that is no longer needed now that the firmware
supports the functionality.  Adds support for ethtool selftestto the ice
driver, which includes testing link, interrupts, eeprom, registers and
packet loopback.  Also, cleaned up duplicate code.

Tony implements support for toggling receive VLAN filter via ethtool.

Brett bumps up the minimum receive descriptor count per queue to resolve
dropped packets.  Refactored the interrupt tracking for the ice driver
to resolve issues seen with the co-existence of features and SR-IOV, so
instead of having a hardware IRQ tracker and a software IRQ tracker,
simply use one tracker.  Also adds a helper function to trigger software
interrupts.

Mitch changes how Malicious Driver Detection (MDD) events are handled,
to ensure all VFs checked for MDD events and just log the event instead
of disabling the VF, which was preventing proper release of resources if
the VF is rebooted or the VF driver reloaded.

Dave cleans up a redundant call to register LLDP MIB change events.

Dan adds support to retrieve the current setting of firmware logging
from the hardware to properly initialize the hardware structure.

Fix gcc build error while CONFIG_INET is not set

drivers/net/ethernet/stmicro/stmmac/stmmac_selftests.o: In function `__stmmac_test_loopback':
stmmac_selftests.c:(.text+0x8ec): undefined reference to `ip_send_check'
stmmac_selftests.c:(.text+0xacc): undefined reference to `udp4_hwcsum'

Add CONFIG_INET dependency to fix this.

This patch moves common code between rht_ptr and rht_ptr_exclusive
into __rht_ptr.  It also adds a new helper rht_ptr_rcu exclusively
for the RCU case.  This way rht_ptr becomes a lock-only construct
so we can use the lighter rcu_dereference_protected primitive.

Before the netdev is registered, calling netdev_info() will emit
something as "(unnamed net device) (uninitialized)", looks confusing.

Before this patch:

In order to initialize the current status of the FW logging,
this patch adds ice_get_fw_log_cfg. The function retrieves
the current setting of the FW logging from HW and updates the
ice_hw structure accordingly.
