Since the array of supported header fields will be used for
Rx flow classification as well, rename it from "hash_fields" to
the more inclusive "dist_fields".

The Management Complex (MC) firmware initially allowed the
configuration of a single key to be used both for Rx flow hashing
and flow classification. This prevented us from supporting
Rx flow classification through ethtool.
Starting with version 10.7.0, the Management Complex(MC) offers
a new set of APIs for separate configuration of Rx hashing and
classification keys.
Update the Rx flow hashing support to use the new API, if available.

====================
100GbE Intel Wired LAN Driver Updates 2018-10-02
This series contains updates to ice driver only.
Anirudh expands the use of VSI handles across the rest of the driver,
which includes refactoring the code to correctly use VSI handles. After
a reset, ensure that all configurations for a VSI get re-applied before
moving on to rebuilding the next VSI.
Dave fixed the driver to check the current link state after reset to
ensure that the correct link state of a port is reported. Fixed an
issue where if the driver is unloaded when traffic is in progress,
errors are generated.
Preethi breaks up the IRQ tracker into a software and hardware IRQ
tracker, where the software IRQ tracker tracks only the PF's IRQ
requests and does not play any role in the VF initialization. The
hardware IRQ tracker represents the device's interrupt space and will be
looked up to see if the device has run our of interrupts when a
interrupt has to be allocated in the device for either PF or VF.
Md Fahad adds support for enabling/disabling RSS via ethtool.
Brett aligns the ice_reset_req enum values to the values that the
hardware understands. Also added initial support for dynamic interrupt
moderation in the ice driver.

Currently there is no support for dynamic interrupt moderation. This
patch adds some initial code to support this. The following changes
were made:
1. Currently we are using multiple members to store the interrupt
granularity (itr_gran_25/50/100/200). This is not necessary because
we can query the device to determine what the interrupt granularity
should be set to, done by a new function ice_get_itr_intrl_gran.
2. Added intrl to ice_q_vector structure to support interrupt rate
limiting.
3. Added the function ice_intrl_usecs_to_reg for converting to a value
in usecs that the device understands.
4. Added call to write to the GLINT_RATE register. Disable intrl by
default for now.
5. Changed rx/tx_itr_setting to itr_setting because having both seems
redundant because a ring is either Tx or Rx.
6. Initialize itr_setting for both Tx/Rx rings in ice_vsi_alloc_rings()

Currently the ice_reset_req enum values have to be translated into
a different set of values that the hardware understands for the same
reset types. Avoid this translation by aligning ice_reset_req enum
values to the ones that the hardware understands.
Also add and else if block to check for ICE_RESET_EMPR and put a dev_dbg
message in the else case.

For the PF driver, when mapping interrupts to queues, we need to request
IRQs from the kernel and we also have to allocate interrupts from
the device.
Similarly, when the VF driver (iavf.ko) initializes, it requests the kernel
IRQs that it needs but it can't directly allocate interrupts in the device.
Instead, it sends a mailbox message to the ice driver, which then allocates
interrupts in the device on the VF driver's behalf.
Currently both these cases end up having to reserve entries in
pf->irq_tracker but irq_tracker itself is sized based on how many vectors
the PF driver needs. Under the right circumstances, the VF driver can fail
to get entries in irq_tracker, which will result in the VF driver failing
probe.
To fix this, sw_irq_tracker and hw_irq_tracker are introduced. The
sw_irq_tracker tracks only the PF's IRQ request and doesn't play any
role in VF init. hw_irq_tracker represents the device's interrupt space.
When interrupts have to be allocated in the device for either PF or VF,
hw_irq_tracker will be looked up to see if the device has run out of
interrupts.

We are currently replaying the link state of a port after a reset, but
it is possible that the link state of a port can change during the reset
process. So check for the current link state of a port during the rebuild
process of a reset.

Currently, switch filters get replayed after reset. In addition to
filters, other VSI attributes (like RSS configuration, Tx scheduler
configuration, etc.) also need to be replayed after reset.
Thus, instead of replaying based on functional blocks (i.e. replay
all filters for all VSIs, followed by RSS configuration replay for
all VSIs, and so on), it makes more sense to have the replay centered
around a VSI. In other words, replay all configurations for a VSI before
moving on to rebuilding the next VSI.
To that effect, this patch introduces a VSI replay framework in a new
function ice_vsi_replay_all. Currently it only replays switch filters,
but it will be expanded in the future to replay additional VSI attributes.

A VSI handle is just a number the driver maintains to uniquely identify
a VSI. A VSI handle is backed by a VSI number in the hardware. When
interacting when the hardware, VSI handles are converted into VSI numbers.
In commit 0f9d5027a749 ("ice: Refactor VSI allocation, deletion and
rebuild flow"), VSI handles were introduced but it was used only
when creating and deleting VSIs. This patch is part one of two patches
that expands the use of VSI handles across the rest of the driver. Also
in this patch, certain parts of the code had to be refactored to correctly
use VSI handles.

When choosing channel amounts and ring sizes, the maximums in the
ibmvnic driver are defined by the virtual i/o server management
partition. Even though they are defined as maximums, the client
driver may in fact successfully request resources that exceed
these limits, which are mostly dependent on a user's hardware
With this in mind, provide an ethtool flag that when enabled will
allow the user to request resources limited by driver-defined
maximums instead of limits defined by the management partition.
The driver will try to honor the user's request but may not allowed
by the management partition. In this case, the driver requests
as close as it can get to the desired amount until it succeeds.

In preparation for unconditionally enabling TX and RX checksum offloads,
refactor bcm_sysport_set_features() a bit such that
__netdev_update_features() during register_netdev() can make sure that
features are correctly programmed during network device registration.
Since we can now be called during register_netdev() with clocks gated,
we need to temporarily turn them on/off in order to have a successful
register programming.
We also move the CRC forward setting read into
bcm_sysport_set_features() since priv->crc_fwd matters while turning on
RX checksum offload, that way we are guaranteed they are in sync in case
we ever add support for NETIF_F_RXFCS at some point in the future.

Each flow director rule consists of input key and action. The input key
is the condition for matching, includes tuples of L2/L3/L4 header.
Action is the behaviour when a packet matches with the input key, such
as drop the packet, or forward to a specified queue.
The input key is stored in the tcam blocks, Each bit of input key can
be masked.

Flow director is a new feature supported by hardware with revision 0x21.
This patch adds flow direcor initialization for each PF. It queries flow
director mode and tcam resource from firmware, selects tuples used for
input key.

This is one step in allowing phylib to make use of link_mode bitmaps,
instead of u32 for supported and advertised features. Convert the phy
drivers to use bitmaps to indicates the features they support.
Build bitmap equivalents of the u32 values at runtime, and have the
drivers point to the appropriate bitmap. These bitmaps are shared, and
we don't want a driver to modify them. So mark them __ro_after_init.
Within phylib, the features bitmap is currently turned back into a
u32. This will be removed once the whole of phylib, and the drivers
are converted to use bitmaps.

The macro PHY_GBIT_FEAUTRES needs to change into a bitmap in order to

offloads code to determine if two mlx5 devices belong to the same
ASIC while adding flows.
Read this once and save it on the core device rather than querying each
time an offloaded flow is added.

Increased the amount of channels the representors can open to be the
amount of CPUs. The default amount opened remains one.
Used the standard NIC netdev functions to:
* Set RSS params when building the representors' params.
* Setup an indirect TIR and RQT for the representors upon
initialization.
* Create a TTC flow table for the representors' indirect TIR (when
creating the TTC table, mlx5e_set_ttc_basic_params() is not called,
in order to avoid setting the inner_ttc param, which is not needed).
Added ethtool control to the representors for setting and querying
the amount of open channels. Additionally, included logic in the
representors' ethtool set channels handler which controls a
representor's vport rx rule, so that if there is one open channel
the rx rule steers traffic to the representor's direct TIR, whereas
if there is more than one channel, the rx rule steers traffic to the
new TTC flow table.

Enabled checksum and TSO offloads for the representors, in
order to increase their performance, which is required to
increase the performance of flows that cannot be offloaded.
Checksum offloads contribute to a general acceleration of all
traffic (to around 150%), whereas the TSO offload contributes
to a prominent acceleration of the representor's TX for traffic
flows with larger than MTU sized packets (to around 200%). This
is the usual case for TCP streams, as the PF, which serves as
the uplink representor, and the VF representors employ GRO before
forwarding the packets to the representor.
GRO was enabled implicitly for the representors beforehand, and
is explicitly enabled here to ensure that the representors preserve
the performance boost it provides (of around 200%) when working in
tandem with the TSO offload by the forwardee, which is the standard
case as both the PF and the VF representors employ HW TSO.
The impact of these changes can be seen in the following
measurements taken on a setup of a VM over a VF, connected
to OVS via the VF representor, to an external host:
Before current changes:
TCP Throughput [Gb/s]
External host to VM ~ 10.5
VM to external host ~ 23.5
With just checksum offloads enabled:
TCP Throughput [Gb/s]
External host to VM ~ 14.9
VM to external host ~ 28.5
With the TSO offload also enabled:
TCP Throughput [Gb/s]
External host to VM ~ 30.5

The representors' RQ size was not large enough for them to achieve
high enough performance, and therefore needed to be enlarged, while
suffering a minimum hit to its memory usage. To achieve this the
representors RQ size was increased, and its type was changed to be a
striding RQ if it is supported.
Towards that goal the following changes were made:
* Extracted the sequence for setting the standard netdev's RQ parmas
into a function
* Replaced the sequence for setting the representor's RQ params with
the standard sequence
The impact of this change can be seen in the following measurements
taken on a setup of a VM over a VF, connected to OVS via the VF
representor, to an external host:
Before current change:
TCP Throughput [Gb/s]
VM to external host ~ 7.2
With the current change (measured with a striding RQ):
TCP Throughput [Gb/s]
VM to external host ~ 23.5
Each representor now consumes 2 [MB] of memory for its packet
buffers.

100GbE Intel Wired LAN Driver Updates 2018-10-01
This series contains updates to ice driver only.
Anirudh provides several changes to "prep" the driver for upcoming
features. Specifically, the functions that are used for PF VSI/netdev
setup will also be used in SR-IOV support and to allow the reuse of
these functions, code needs to move.
Dave provides the only other change in the series, updates the driver to
protect the reset patch in its entirety. This is done by adding the
various bit checks to determine if a reset is scheduled/initiated and
whether it came from the software or firmware.

Currently, there is no bit, or set of bits, that protect the entirety
of the reset path.
If the reset is originated by the driver, then the relevant
one of the following bits will be set when the reset is scheduled:
__ICE_PFR_REQ
__ICE_CORER_REQ
__ICE_GLOBR_REQ
This bit will not be cleared until after the rebuild has completed.
If the reset is originated by the FW, then the first the driver knows of
it will be the reception of the OICR interrupt. The __ICE_RESET_OICR_RECV
bit will be set in the interrupt handler. This will also be the indicator
in a SW originated reset that we have completed the pre-OICR tasks and
have informed the FW that a reset was requested.
To utilize these bits, change the function:
ice_is_reset_recovery_pending()
to be:
ice_is_reset_in_progress()
The new function will check all of the above bits in the pf->state and
will return a true if one or more of these bits are set.
