When a switch rule is initially created we set the filter action to
ICE_FWD_TO_VSI. The filter action changes to ICE_FWD_TO_VSI_LIST
whenever more than one VSI is subscribed to the same switch rule. When
the switch rule goes from 2 VSIs in the list to 1 VSI we remove and
delete the VSI list rule, but we currently don't update the switch rule
in hardware. This is causing switch rules to be lost, so fix that by
making a call to ice_update_pkt_fwd_rule() with the necessary changes.

virtchnl is a protocol/interface specification that allows the Intel
"Adaptive Virtual Function (AVF)" driver (iavf.ko) to work with more than
one physical function driver. The AVF driver sends "virtchnl commands"
(control plane only) to the PF driver over mailbox queues and the PF driver
executes these commands and returns a result to the VF, again over mailbox.
This patch adds AVF support for the ice PF driver by implementing the
following virtchnl commands:
VIRTCHNL_OP_VERSION
VIRTCHNL_OP_GET_VF_RESOURCES
VIRTCHNL_OP_RESET_VF
VIRTCHNL_OP_ADD_ETH_ADDR
VIRTCHNL_OP_DEL_ETH_ADDR
VIRTCHNL_OP_CONFIG_VSI_QUEUES
VIRTCHNL_OP_ENABLE_QUEUES
VIRTCHNL_OP_DISABLE_QUEUES

VIRTCHNL_OP_DEL_ETH_ADDR
VIRTCHNL_OP_CONFIG_VSI_QUEUES
VIRTCHNL_OP_ENABLE_QUEUES
VIRTCHNL_OP_DISABLE_QUEUES
VIRTCHNL_OP_REQUEST_QUEUES
VIRTCHNL_OP_CONFIG_IRQ_MAP
VIRTCHNL_OP_CONFIG_RSS_KEY
VIRTCHNL_OP_CONFIG_RSS_LUT
VIRTCHNL_OP_GET_STATS
VIRTCHNL_OP_ADD_VLAN
VIRTCHNL_OP_DEL_VLAN

Post VF initialization, there are a couple of different ways in which a
VF reset can be triggered. One is when the underlying PF itself goes
through a reset and other is via a VFLR interrupt. ice_reset_vf introduced
in this patch handles both these cases.
Also introduced in this patch is a helper function ice_aq_send_msg_to_vf
to send messages to VF over the mailbox queue. The PF uses this to send
reset notifications to VFs.

This patch implements parts of ice_sriov_configure and VF reset flow.
To create virtual functions (VFs), the user sets a value in num_vfs
through sysfs. This results in the kernel calling the handler for
.sriov_configure which is ice_sriov_configure.
VF setup first starts with a VF reset, followed by allocation of the VF
VSI using ice_vf_vsi_setup. Once the VF setup is complete a state bit
ICE_VF_STATE_INIT is set in the vf->states bitmap to indicate that
the VF is ready to go.
Also for VF reset to go into effect, it's necessary to issue a disable
queue command (ice_aqc_opc_dis_txqs). So this patch updates multiple
functions in the disable queue flow to take additional parameters that
distinguish if queues are being disabled due to VF reset.

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'.

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.

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.

While the old field was implicitly initialized to 0, the new field is

Fix this by explicitly initializing the option.

We support classification based on some header fields for

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.

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()

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.

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
