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
size transactions are used.

Add call to configure dropping egress LLDP packets in ice_vsi_setup
and remove the rule in ice_vsi_release.
Add calls to add/remove rule to route LLDP packets to default VSI when
FW LLDP engine is disabled/enabled and remove rule if applied during
ice_vsi_release.
In the function ice_add_eth_mac(), there is a line that hard codes the
filter info flag to TX. This is incorrect as this flag will be set by
the calling function that built the list of filters to add. So remove
the hard coded value.
This patch also contains a fix to stop treating the DCBx state of
"Not Started" as an error state that kicks DCB in SW mode. This will
address having non-cabled interfaces automatically go into SW mode

Add support for virtchnl_vector_map.[rxq|txq]_map to use bitmap to
associate indicated queues with the specified vector. This support is
needed since the Windows AVF driver calls VIRTCHNL_OP_CONFIG_IRQ_MAP for
each vector and used the bitmap to indicate the associated queues.
Updated ice_vc_dis_qs_msg to not subtract one from
virtchnl_irq_map_info.num_vectors, and changed the VSI vector index to
the vector id. This change supports the Windows AVF driver which maps
one vector at a time and sets num_vectors to one. Using vectors_id to
index the vector array .

Currently in ice_free_vf_res() we are writing to the VFINT_DYN_CTLN
register in the PF's function space to disable all VF's interrupts. This
is incorrect because this register is only for use in the VF's function
space. This becomes obvious when seeing that the valid indices used for
the VFINT_DYN_CTLN register is from 0-63, which is the maximum number of
interrupts for a VF (not including the OICR interrupt). Fix this by
writing to the GLINT_DYN_CTL register for each VF. We can do this
because we keep track of each VF's first_vector_idx inside of the PF's
function space and the number of interrupts given to each VF.
Also in ice_free_vfs() we were disabling Rx/Tx queues after calling
pci_disable_sriov(). One part of disabling the Tx queues causes the PF
driver to trigger a software interrupt, which causes the VF's napi
routine to run. This doesn't currently work because pci_disable_sriov()
causes iavf_remove() to be called which disables interrupts. Fix this by
disabling Rx/Tx queues prior to pci_disable_sriov().

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 aab9c4067d2389d0adfc9c53806437df7b0fe3d5
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.

In the PHYLINK_DEV operation type, the PHYLINK infrastructure can work
without an attached net_device. For printing usecases, instead, a struct
device * should be passed to PHYLINK using the phylink_config structure.
Also, netif_carrier_* calls ar guarded by the presence of a valid
net_device. When using the PHYLINK_DEV operation type, we cannot check
link status using the netif_carrier_ok() API so instead, keep an
internal state of the MAC and call mac_link_{down,up} only when the link
changed.

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.

A prerequisite for PHYLIB to work in the absence of a struct net_device
is to not access pointers to it.
Changes are needed in the following areas:
- Printing: In some places netdev_err was replaced with phydev_err.
- Incrementing reference count to the parent MDIO bus driver: If there
is no net device, then the reference count should definitely be
incremented since there is no chance that it was an Ethernet driver
who registered the MDIO bus.
- Sysfs links are not created in case there is no attached_dev.
- No netif_carrier_off is done if there is no attached_dev.

MAC on the GBit versions supports 1000/Full only, however the PHY
partially claims to support 1000/Half. So let's explicitly remove
this mode.

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.

PHY_INTERFACE_MODE_RGMII_RXID is less then TXID
so code to set tx delay is never called.

After reset SGMII Autoneg timer is set to 2us (bits 6 and 5 are 01).
That is not enough to finalize autonegatiation on some devices.
Increase this timer duration to maximum supported 16ms.

For supporting 10Mps speed in SGMII mode DP83867_10M_SGMII_RATE_ADAPT bit
of DP83867_10M_SGMII_CFG register has to be cleared by software.
That does not affect speeds 100 and 1000 so can be done on init.

Some boards do not have the PHY firmware programmed in the 3310's flash,
which leads to the PHY not working as expected. Warn the user when the
PHY fails to boot the firmware and refuse to initialise.
