34e141eea7 ath10k: fix possible out of bound access of ath10k_rates array
While using 'ath10k_mac_get_rate_hw_value()' to obtain the hw value
from the passed bitrate, there is a chance of out of bound array access
when wrong bitrate is passed. This is fixed by comparing the bitrates
within the correct size of the ath10k_rates array.

Fixes commit f279294e9e ("ath10k: add support for configuring management
packet rate"). Also correction made to some indents used in the above commit.

4e6d47206c tls: Add support for inplace records encryption
Presently, for non-zero copy case, separate pages are allocated for
storing plaintext and encrypted text of records. These pages are stored
in sg_plaintext_data and sg_encrypted_data scatterlists inside record
structure. Further, sg_plaintext_data & sg_encrypted_data are passed
to cryptoapis for record encryption. Allocating separate pages for
plaintext and encrypted text is inefficient from both required memory
and performance point of view.

This patch adds support of inplace encryption of records. For non-zero
copy case, we reuse the pages from sg_encrypted_data scatterlist to
copy the application's plaintext data. For the movement of pages from
sg_encrypted_data to sg_plaintext_data scatterlists, we introduce a new
function move_to_plaintext_sg(). This function add pages into
sg_plaintext_data from sg_encrypted_data scatterlists.

tls_do_encryption() is modified to pass the same scatterlist as both
source and destination into aead_request_set_crypt() if inplace crypto
has been enabled. A new ariable 'inplace_crypto' has been introduced in
record structure to signify whether the same scatterlist can be used.
By default, the inplace_crypto is enabled in get_rec(). If zero-copy is
used (i.e. plaintext data is not copied), inplace_crypto is set to '0'.

2a7f8c3b1d hv_netvsc: remove ndo_poll_controller
Similar to other patches from ERic.

As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.

In netvsc driver it uses NAPI for TX completions. The default
poll_napi will do this for us now and avoid the capture.

854da99173 ipv4: Allow sending multicast packets on specific i/f using VRF socket
It is useful to be able to use the same socket for listening in a
specific VRF, as for sending multicast packets out of a specific
interface. However, the bound device on the socket currently takes
precedence and results in the packets not being sent.

Relax the condition on overriding the output interface to use for
sending packets out of UDP, raw and ping sockets to allow multicast
packets to be sent using the specified multicast interface.

6919622af3 bridge: mcast: Default back to multicast enabled state
Commit 13cefad2f2 ("net: bridge: convert and rename mcast disabled")
converted the 'multicast_disabled' field to an option bit named
'BROPT_MULTICAST_ENABLED'.

While the old field was implicitly initialized to 0, the new field is
not initialized, resulting in the bridge defaulting to multicast
disabled state and breaking existing applications.

Fix this by explicitly initializing the option.

====================
dpaa2-eth: Add support for Rx flow classification

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 independently of the hash key configuration.

Newer firmware versions expose separate commands for
configuring the two types of keys, so we can use them to
introduce Rx classification support. For frames that don't match
any classification rule, we fall back to statistical distribution
based on the current hash key.

The first patch in this set updates the Rx hashing code to use
the new firmware API for key config. Subsequent patches introduce
the firmware API for configuring the classification and actual
support for adding and deleting rules via ethtool.

Add support for inserting and deleting Rx flow classification
rules through ethtool.

We support classification based on some header fields for
flow-types ether, ip4, tcp4, udp4 and sctp4.

Rx queues are core affine, so the action argument effectively
selects on which cpu the matching frame will be processed.
Discarding the frame is also supported.

4aaaf9b95a dpaa2-eth: Configure Rx flow classification key
For firmware versions that support it, configure an Rx flow
classification key at probe time.

Hardware expects all rules in the classification table to share
the same key. So we setup a key containing all supported fields
at driver init and when a user adds classification rules through
ethtool, we will just mask out the unused header fields.

Since the key composition process is the same for flow
classification and hashing, reuse existing code where possible.

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.

9e4ab4c29a ice: Add support for dynamic interrupt moderation
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

eb0208ec42 ice: Split irq_tracker into sw_irq_tracker and hw_irq_tracker
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.

5755143dd1 ice: Check for actual link state of port after reset

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

334cb0626d ice: Implement VSI replay framework
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.

5726ca0e5e ice: Expand use of VSI handles part 1/2
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 0f9d5027a7 ("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.

====================
ibmvnic: Implement driver-defined queue limits

In this patch series, update the ibmvnic driver to use driver-defined
queue limits instead of limits imposed by the Virtual I/O server
management partition. For some deviced, initial max queue size and
amount limits, despite their definition, can actually be exceeded if
the client driver requests it. With this in mind, define a private
ethtool flag that toggles the use of driver-defined limits. These
limits are currently more than what supported hardware will likely
allow, so the driver will attempt to get as close as possible to
the user request but may not fully succeed.

723ad91613 ibmvnic: Add ethtool private flag for driver-defined queue limits
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.
