Get link status version 2 (opcode 0x0607) is returning an error because FW
expects a data length of 56 bytes, and this is causing the driver to fail
probe.
Update the get link status version 2 data length to 56 bytes by adding 5
byte reserved5 field to the end of struct ice_aqc_get_link_status_data and
passing it as parameter to offsetofend() to the fix error.

Add const modifier to function parameters and variables where appropriate
in ice_base.c and corresponding declarations in ice_base.h.
The reason for starting the change is that read-only pointers should be
marked as const when possible to allow for smoother and more optimal code
generation and optimization as well as allowing the compiler to warn the
developer about potentially unwanted modifications, while not carrying
noticeable negative impact.

It was found that this statistic is incorrectly

As RX length error statistics are shown to the

Thus, that value is no longer reported and

The ice_vf_create_vsi() function and its VF ops helper introduced by commit
a4c785e8162e ("ice: convert vf_ops .vsi_rebuild to .create_vsi") are used
during an individual VF reset to re-create the VSI. This was done in order
to ensure that the VSI gets properly reconfigured within the hardware.
This is somewhat heavy handed as we completely release the VSI memory and
structure, and then create a new VSI. This can also potentially force a
change of the VSI index as we will re-use the first open slot in the VSI
array which may not be the same.
As part of implementing devlink reload, commit 6624e780a577 ("ice: split
ice_vsi_setup into smaller functions") split VSI setup into smaller
functions, introducing both ice_vsi_cfg() and ice_vsi_decfg() which can be
used to configure or deconfigure an existing software VSI structure.
Rather than completely removing the VSI and adding a new one using the
.create_vsi() VF operation, simply use ice_vsi_decfg() to remove the
current configuration. Save the VSI type and then call ice_vsi_cfg() to
reconfigure the VSI as the same type that it was before.
The existing reset logic assumes that all hardware filters will be removed,
so also call ice_fltr_remove_all() before re-configuring the VSI.
This new operation does not re-create the VSI, so rename it to
ice_vf_reconfig_vsi().
The new approach can safely share the exact same flow for both SR-IOV VFs
as well as the Scalable IOV VFs being worked on. This uses less code and is
a better abstraction over fully deleting the VSI and adding a new one.

Introduce new capability - Low Latency Timestamping with Interrupt.
On supported devices, driver can request a single timestamp from FW
without polling the register afterwards. Instead, FW can issue
a dedicated interrupt when the timestamp was read from the PHY register
and its value is available to read from the register.
This eliminates the need of bottom half scheduling, which results in
minimal delay for timestamping.
For this mode, allocate TS indices sequentially, so that timestamps are
always completed in FIFO manner.

Stop dividing the phase_offset value received from firmware. This fault
is present since the initial implementation.
The phase_offset value received from firmware is in 0.01ps resolution.
Dpll subsystem is using the value in 0.001ps, raw value is adjusted
before providing it to the user.
The user can observe the value of phase offset with response to
`pin-get` netlink message of dpll subsystem for an active pin:
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-get --json '{"id":2}'
Where example of correct response would be:
{'board-label': 'C827_0-RCLKA',

'clock-id': 4658613174691613800,
'frequency': 1953125,

'phase-adjust': 0,
'phase-adjust-max': 16723,

Provided phase-offset value (-42930) shall be divided by the user with

====================
intel: use bitfield operations
Jesse Brandeburg says:
After repeatedly getting review comments on new patches, and sporadic
patches to fix parts of our drivers, we should just convert the Intel code
to use FIELD_PREP() and FIELD_GET(). It's then "common" in the code and
hopefully future change-sets will see the context and do-the-right-thing.
This conversion was done with a coccinelle script which is mentioned in the
commit messages. Generally there were only a couple conversions that were
"undone" after the automatic changes because they tried to convert a
non-contiguous mask.
Patch 1 is required at the beginning of this series to fix a "forever"
issue in the e1000e driver that fails the compilation test after conversion
because the shift / mask was out of range.
The second patch just adds all the new #includes in one go.
The patch titled: "ice: fix pre-shifted bit usage" is needed to allow the
use of the FIELD_* macros and fix up the unexpected "shifts included"
defines found while creating this series.
The rest are the conversion to use FIELD_PREP()/FIELD_GET(), and the
occasional leXX_{get,set,encode}_bits() call, as suggested by Alex.

Alexei Starovoitov says:
====================
pull-request: bpf-next 2023-12-18
This PR is larger than usual and contains changes in various parts
of the kernel.
The main changes are:
1) Fix kCFI bugs in BPF, from Peter Zijlstra.
End result: all forms of indirect calls from BPF into kernel
and from kernel into BPF work with CFI enabled. This allows BPF
to work with CONFIG_FINEIBT=y.
2) Introduce BPF token object, from Andrii Nakryiko.
It adds an ability to delegate a subset of BPF features from privileged
daemon (e.g., systemd) through special mount options for userns-bound
BPF FS to a trusted unprivileged application. The design accommodates
suggestions from Christian Brauner and Paul Moore.
Example:
$ sudo mkdir -p /sys/fs/bpf/token
$ sudo mount -t bpf bpffs /sys/fs/bpf/token \
-o delegate_cmds=prog_load:MAP_CREATE \
-o delegate_progs=kprobe \
-o delegate_attachs=xdp
3) Various verifier improvements and fixes, from Andrii Nakryiko, Andrei Matei.
- Complete precision tracking support for register spills
- Fix verification of possibly-zero-sized stack accesses
- Fix access to uninit stack slots
- Track aligned STACK_ZERO cases as imprecise spilled registers.
It improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs.
- Fix verifier retval logic
4) Support for VLAN tag in XDP hints, from Larysa Zaremba.
5) Allocate BPF trampoline via bpf_prog_pack mechanism, from Song Liu.
End result: better memory utilization and lower I$ miss for calls to BPF
via BPF trampoline.
6) Fix race between BPF prog accessing inner map and parallel delete,
from Hou Tao.
7) Add bpf_xdp_get_xfrm_state() kfunc, from Daniel Xu.
It allows BPF interact with IPSEC infra. The intent is to support
software RSS (via XDP) for the upcoming ipsec pcpu work.
Experiments on AWS demonstrate single tunnel pcpu ipsec reaching
line rate on 100G ENA nics.
8) Expand bpf_cgrp_storage to support cgroup1 non-attach, from Yafang Shao.
9) BPF file verification via fsverity, from Song Liu.
It allows BPF progs get fsverity digest.

It was found while doing further testing of the previous commit
fbf32a9bab91 ("ice: field get conversion") that one of the FIELD_GET
conversions should really be a FIELD_PREP. The previous code was styled
as a match to the FIELD_GET conversion, which always worked because the
shift value was 0. The code makes way more sense as a FIELD_PREP and
was in fact the only FIELD_GET with two constant arguments in this
series.
Didn't squash this patch to make it easier to call out the
(non-impactful) bug.

While converting to FIELD_PREP() and FIELD_GET(), it was noticed that
some of the RSS defines had *included* the shift in their definitions.
This is completely outside of normal, such that a developer could easily
make a mistake and shift at the usage site (like when using
FIELD_PREP()).
Rename the defines and set them to the "pre-shifted values" so they
match the template the driver normally uses for masks and the member
bits of the mask, which also allows the driver to use FIELD_PREP
correctly with these values. Use GENMASK() for this changed MASK value.
Do the same for the VLAN EMODE defines as well.

Several places I changed to OR into a single variable with |= instead of

A local variable vmvf_and_timeout was created and used to avoid multiple
logical ORs being __le16 converted, which shortened some lines and makes
the code cleaner.
Also clean up a couple of places where conversions were made to have the

Previously, the ice driver had support for using a handler for bonding
netdev events to ensure that conflicting features were not allowed to be
activated at the same time. While this was still in place, additional
support was added to specifically support SRIOV and LAG together. These
both utilized the netdev event handler, but the SRIOV and LAG feature was
behind a capabilities feature check to make sure the current NVM has
support.
The exclusion part of the event handler should be removed since there are
users who have custom made solutions that depend on the non-exclusion of
features.
Wrap the creation/registration and cleanup of the event handler and
associated structs in the probe flow with a feature check so that the
only systems that support the full implementation of LAG features will
initialize support. This will leave other systems unhindered with
functionality as it existed before any LAG code was added.

When creating new VSIs, they are assigned into an aggregator node in the
scheduler tree. Information about which aggregator node a VSI is assigned
into is maintained by the vsi->agg_node structure. In ice_vsi_decfg(), this
information is being destroyed, by overwriting the valid flag and the
agg_id field to zero.
For VF VSIs, this breaks the aggregator node configuration replay, which
depends on this information. This results in VFs being inserted into the
default aggregator node. The resulting configuration will have unexpected
Tx bandwidth sharing behavior.
This was broken by commit 6624e780a577 ("ice: split ice_vsi_setup into
smaller functions"), which added the block to reset the agg_node data.
The vsi->agg_node structure is not managed by the scheduler code, but is
instead a wrapper around an aggregator node ID that is tracked at the VSI
layer. Its been around for a long time, and its primary purpose was for
handling VFs. The SR-IOV VF reset flow does not make use of the standard VSI
rebuild/replay logic, and uses vsi->agg_node as part of its handling to
rebuild the aggregator node configuration.
The logic for aggregator nodes stretches back to early ice driver code from
commit b126bd6bcd67 ("ice: create scheduler aggregator node config and move
VSIs")
The logic in ice_vsi_decfg() which trashes the ice_agg_node data is clearly
wrong. It destroys information that is necessary for handling VF reset,. It
is also not the correct way to actually remove a VSI from an aggregator
node. For that, we need to implement logic in the scheduler code. Further,
non-VF VSIs properly replay their aggregator configuration using existing
scheduler replay logic.
To fix the VF replay logic, remove this broken aggregator node cleanup
logic. This is the simplest way to immediately fix this.
This ensures that VFs will have proper aggregate configuration after a
reset. This is especially important since VFs often perform resets as part
of their reconfiguration flows. Without fixing this, VFs will be placed in
the default aggregator node and Tx bandwidth will not be shared in the
expected and configured manner.

Once logging is enabled the user should read the data from the 'data'
file. The data is in the form of a binary blob that can be sent to Intel
for decoding. To read the data use a command like:
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data > log_data.bin
If the user wants to clear the FW log data that has been stored in the
driver then they can write any value to the 'data' file and that will clear
the data. An example is:
# echo 34 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data
In addition to being able to read the data the user can configure how
much memory is used to store FW log data. This allows the user to
increase/decrease the amount of memory based on the users situation.
The data is stored such that if the memory fills up then the oldest data
will get overwritten in a circular manner. To change the amount of
memory the user can write to the 'log_size' file like this:
# echo <value> > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/log_size
Where <value> is one of 128K, 256K, 512K, 1M, and 2M. The default value
is 1M.
The user can see the current value of 'log_size' by reading the file:
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/log_size

Once users have configured the FW logging then allow them to enable it
by writing to the 'fwlog/enable' file. The file accepts a boolean value
(0 or 1) where 1 means enable FW logging and 0 means disable FW logging.
# echo <value> > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/enable
Where <value> is 0 or 1.
The user can read the 'fwlog/enable' file to see whether logging is
enabled or not. Reading the actual data is a separate patch. To see the
current value then:

Users want the ability to debug FW issues by retrieving the
FW logs from the E8xx devices. Use debugfs to allow the user to
configure the log level and number of messages for FW logging.
If FW logging is supported on the E8xx then the file 'fwlog' will be
created under the PCI device ID for the ice driver. If the file does not
exist then either the E8xx doesn't support FW logging or debugfs is not
enabled on the system.
One thing users want to do is control which events are reported. The
user can read and write the 'fwlog/modules/<module name>' to get/set
the log levels. Each module in the FW that supports logging ht as a file
under 'fwlog/modules' that supports reading (to see what the current log
level is) and writing (to change the log level).
The format to set the log levels for a module are:
# echo <log level> > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/<module>
The supported log levels are:
* none
* error
* warning
* normal
* verbose
Each level includes the messages from the previous/lower level
The modules that are supported are:
* general
* ctrl
* link
* link_topo
* dnl
* i2c
* sdp
* mdio
* adminq
* hdma
* lldp
* dcbx
* dcb
* xlr
* nvm
* auth
* vpd
* iosf
* parser
* sw
* scheduler
* txq
* rsvd
* post
* watchdog
* task_dispatch
* mng
* synce
* health
* tsdrv
* pfreg
* mdlver
* all
The module 'all' is a special module which allows the user to read or
write to all of the modules.
The following example command would set the DCB module to the 'normal'
log level:
# echo normal > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/dcb
If the user wants to set the DCB, Link, and the AdminQ modules to
'verbose' then the commands are:
# echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/dcb
# echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/link
# echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/adminq
If the user wants to set all modules to the 'warning' level then the
command is:
# echo warning > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/all
If the user wants to disable logging for a module then they can set the
level to 'none'. An example setting the 'watchdog' module is:
# echo none > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/watchdog
If the user wants to see what the log level is for a specific module
then the command is:
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/dcb
This will return the log level for the DCB module. If the user wants to
see the log level for all the modules then the command is:
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/all
Writing to the module file will update the configuration, but NOT enable the
configuration (that is a separate command).
In addition to configuring the modules, the user can also configure the
number of log messages (nr_messages) to include in a single Admin Receive
Queue (ARQ) event.The range is 1-128 (1 means push every log message, 128
means push only when the max AQ command buffer is full). The suggested
value is 10.
To see/change the resolution the user can read/write the
'fwlog/nr_messages' file. An example changing the value to 50 is
# echo 50 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/nr_messages
To see the current value of 'nr_messages' then the command is:
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/nr_messages

Allow the user to set the symmetric Toeplitz hash function via:
# ethtool -X eth0 hfunc toeplitz symmetric-xor
All existing RSS configurations will be converted to symmetric unless they
have a non-symmetric field (other than IP src/dst and L4 src/dst ports)
used for hashing. The driver will reject a new RSS configuration if such
a field is requested.
The hash function in the E800 NICs is set per-VSI and a specific AQ
command is needed to modify the hash function. Use the AQ command to
enable setting the symmetric Toeplitz RSS hash function for any VSI
in the new ice_set_rss_hfunc().
When the Symmetric Toeplitz hash function is used, the hardware sets the
input set of the RSS (Toeplitz) algorithm to be the XOR of the fields
index by HSYMM and the fields index by the INSET registers. We use this
to create a symmetric hash by setting the HSYMM registers to point to
their counterparts in the INSET registers:
HSYMM [src_fv] = dst_fv;
HSYMM [dst_fv] = src_fv;
where src_fv and dst_fv are the indexes of the protocol's src and dst
fields.

pass it as an argument to several functions.
Also introduce enum ice_rss_cfg_hdr_type to specify a more granular and
flexible RSS configuration:
ICE_RSS_OUTER_HEADERS - take outer layer as RSS input set
ICE_RSS_INNER_HEADERS - take inner layer as RSS input set
ICE_RSS_INNER_HEADERS_W_OUTER_IPV4 - take inner layer as RSS input set for
packet with outer IPV4
ICE_RSS_INNER_HEADERS_W_OUTER_IPV6 - take inner layer as RSS input set for
packet with outer IPV6
ICE_RSS_ANY_HEADERS - try with outer first then inner (same as the
behaviour without this change)
Finally, move the virtchnl_rss_algorithm enum to be with the other RSS
related structures in the virtchnl.h file.
There should be no functional change due to this patch.

The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters
as direct function arguments. This will force us to change the API (and
all drivers' functions) every time some new parameters are added.
This is part 1/2 of the fix, as suggested in [1]:
- First simplify the code by always providing a pointer to all params
(indir, key and func); the fact that some of them may be NULL seems
like a weird historic thing or a premature optimization.
It will simplify the drivers if all pointers are always present.
- Then make the functions take a dev pointer, and a pointer to a
single struct wrapping all arguments. The set_* should also take
an extack.

In AF_XDP ZC, xdp_buff is not stored on ring,
instead it is provided by xsk_buff_pool.
Space for metadata sources right after such buffers was already reserved
in commit 94ecc5ca4dbf ("xsk: Add cb area to struct xdp_buff_xsk").
Some things (such as pointer to packet context) do not change on a
per-packet basis, so they can be set at the same time as RX queue info.
On the other hand, RX descriptor is unique for each packet, but is already
known when setting DMA addresses. This minimizes performance impact of
hints on regular packet processing.

RX hash XDP hint requests both hash value and type.
Type is XDP-specific, so we need a separate way to map
these values to the hardware ptypes, so create a lookup table.
Instead of creating a new long list, reuse contents
of ice_decode_rx_desc_ptype[] through preprocessor.
Current hash type enum does not contain ICMP packet type,
but ice devices support it, so also add a new type into core code.
Then use previously refactored code and create a function

In order to use XDP hints via kfuncs we need to put
RX descriptor and miscellaneous data next to xdp_buff.
Same as in hints implementations in other drivers, we achieve
this through putting xdp_buff into a child structure.
Currently, xdp_buff is stored in the ring structure,
so replace it with union that includes child structure.
This way enough memory is available while existing XDP code
remains isolated from hints.
Minimum size of the new child structure (ice_xdp_buff) is exactly
64 bytes (single cache line). To place it at the start of a cache line,
move 'next' field from CL1 to CL4, as it isn't used often. This still
leaves 192 bits available in CL3 for packet context extensions.

To map phy types reported by the hardware to ethtool link mode bits,
ice uses two lookup tables (phy_type_low_lkup, phy_type_high_lkup).
The "low" table has 64 elements to cover every possible bit the hardware
may report, but the "high" table has only 13. If the hardware reports a
higher bit in phy_types_high, the driver would access memory beyond the
lookup table's end.
Instead of iterating through all 64 bits of phy_types_{low,high}, use
the sizes of the respective lookup tables.

Also delete duplicate lines in ice_port_vlan_on().

vfs::num_msix_per should be only used as default value for
vf->num_msix. For other use cases vf->num_msix should be used, as VF can
have different MSI-X amount values.
Fix incorrect register index calculation. vfs::num_msix_per and
pf->sriov_base_vector shouldn't be used after implementation of changing
MSI-X amount on VFs. Instead vf->first_vector_idx should be used, as it
is storing value for first irq index.

When code is applicable for both E822 and E823 devices, rename it from
E822 to E82X.
ICE_PHY_PER_NAC_E822 was unused, so just remove it.
