Add missing FLOW_DISSECTOR_KEY_ENC_* checks to TC flower filter parsing.
Without these checks, it would be possible to add filters with tunnel
options on non-tunnel devices. enc_* options are only valid for tunnel
devices.
Example:
devlink dev eswitch set $PF1_PCI mode switchdev
echo 1 > /sys/class/net/$PF1/device/sriov_numvfs
tc qdisc add dev $VF1_PR ingress
ethtool -K $PF1 hw-tc-offload on
tc filter add dev $VF1_PR ingress flower enc_ttl 12 skip_sw action drop

The check for flags is done to not pass empty lookups to adding switch
rule functions. Since metadata is always added to lookups there is no
need to check against the flag.
It is also fixing the problem with such rule:
$ tc filter add dev gtp_dev ingress protocol ip prio 0 flower \
enc_dst_port 2123 action drop
Switch block in case of GTP can't parse the destination port, because it
should always be set to GTP specific value. The same with ethertype. The
result is that there is no other matching criteria than GTP tunnel. In
this case flags is 0, rule can't be added only because of defensive
check against flags.

In case of traffic going from the VF (so ingress for port representor)
source VSI should be consider during packet classification. It is
needed for hardware to not match packets from different ports with
filters added on other port.
It is only for "from VF" traffic, because other traffic direction
doesn't have source VSI.
Set correct ::src_vsi in rule_info to pass it to the hardware filter.
For example this rule should drop only ipv4 packets from eth10, not from
the others VF PRs. It is needed to check source VSI in this case.

ice_port_vlan_on/off() was introduced in commit 2946204b3f ("ice:
implement bridge port vlan"). But ice_port_vlan_on() incorrectly assigns
ena_rx_filtering to inner_vlan_ops in DVM mode.
This causes an error when rx_filtering cannot be enabled in legacy mode.

The ice driver would previously panic after suspend. This is caused
from the driver *only* calling the ice_vsi_free_q_vectors() function by
itself, when it is suspending. Since commit b3e7b3a6ee ("ice: prevent
NULL pointer deref during reload") the driver has zeroed out
num_q_vectors, and only restored it in ice_vsi_cfg_def().
This further causes the ice_rebuild() function to allocate a zero length
buffer, after which num_q_vectors is updated, and then the new value of
num_q_vectors is used to index into the zero length buffer, which
corrupts memory.
The fix entails making sure all the code referencing num_q_vectors only
does so after it has been reset via ice_vsi_cfg_def().
I didn't perform a full bisect, but I was able to test against 6.1.77
kernel and that ice driver works fine for suspend/resume with no panic,
so sometime since then, this problem was introduced.
Also clean up an un-needed init of a local variable in the function
being modified.

ethtool: ice: Support for RSS settings to GTP
Takeru Hayasaka enables RSS functionality for GTP packets on ice driver
with ethtool.
A user can include TEID and make RSS work for GTP-U over IPv4 by doing the

In addition to gtpu(4|6), we now support gtpc(4|6),gtpc(4|6)t,gtpu(4|6)e,
gtpu(4|6)u, and gtpu(4|6)d.
gtpc(4|6): Used for GTP-C in IPv4 and IPv6, where the GTP header format does
not include a TEID.
gtpc(4|6)t: Used for GTP-C in IPv4 and IPv6, with a GTP header format that
includes a TEID.
gtpu(4|6): Used for GTP-U in both IPv4 and IPv6 scenarios.
gtpu(4|6)e: Used for GTP-U with extended headers in both IPv4 and IPv6.
gtpu(4|6)u: Used when the PSC (PDU session container) in the GTP-U extended
header includes Uplink, applicable to both IPv4 and IPv6.
gtpu(4|6)d: Used when the PSC in the GTP-U extended header includes Downlink,
for both IPv4 and IPv6.

Following the addition of new GTP RSS hash options to ethtool.h, this patch
implements the corresponding RSS settings for GTP packets in the Intel ice
driver. It enables users to configure RSS for GTP-U and GTP-C traffic over IPv4
and IPv6, utilizing the newly defined hash options.
The implementation covers the handling of gtpu(4|6), gtpc(4|6), gtpc(4|6)t,
gtpu(4|6)e, gtpu(4|6)u, and gtpu(4|6)d traffic, providing enhanced load
distribution for GTP traffic across multiple processing units.

Simplify stats accumulation logic to fix the case where we don't take
previous stat value into account, we should always respect it.
Main netdev stats of our PF (Tx/Rx packets/bytes) were reported orders of
magnitude too big during OpenStack reconfiguration events, possibly other
reconfiguration cases too.
The regression was reported to be between 6.1 and 6.2, so I was almost
certain that on of the two "preserve stats over reset" commits were the
culprit. While reading the code, it was found that in some cases we will
increase the stats by arbitrarily large number (thanks to ignoring "-prev"
part of condition, after zeroing it).
Note that this fixes also the case where we were around limits of u64, but
that was not the regression reported.
Full disclosure: I remember suggesting this particular piece of code to
Ben a few years ago, so blame on me.

Older versions of GCC really want to know the full definition
of the type involved in rcu_assign_pointer().
struct dpll_pin is defined in a local header, net/core can't
reach it. Move all the netdev <> dpll code into dpll, where

The E800 series hardware uses the same iAVF driver as older devices,
including the virtchnl negotiation scheme.
This negotiation scheme includes a mechanism to determine what type of RSS
should be supported, including RSS over PF virtchnl messages, RSS over
firmware AdminQ messages, and RSS via direct register access.
The PF driver will always prefer VIRTCHNL_VF_OFFLOAD_RSS_PF if its
supported by the VF driver. However, if an older VF driver is loaded, it
may request only VIRTCHNL_VF_OFFLOAD_RSS_REG or VIRTCHNL_VF_OFFLOAD_RSS_AQ.
The ice driver happily agrees to support these methods. Unfortunately, the
underlying hardware does not support these mechanisms. The E800 series VFs
don't have the appropriate registers for RSS_REG. The mailbox queue used by
VFs for VF to PF communication blocks messages which do not have the
VF-to-PF opcode.
Stop lying to the VF that it could support RSS over AdminQ or registers, as
these interfaces do not work when the hardware is operating on an E800
series device.
In practice this is unlikely to be hit by any normal user. The iAVF driver
has supported RSS over PF virtchnl commands since 2016, and always defaults
to using RSS_PF if possible.
In principle, nothing actually stops the existing VF from attempting to
access the registers or send an AQ command. However a properly coded VF
will check the capability flags and will report a more useful error if it
detects a case where the driver does not support the RSS offloads that it
does.

The indentation for ice_set_ctx and ice_write_rxq_ctx breaks the function
name after the return type. This style of breaking is used a lot throughout
the ice driver, even in cases where its not actually helpful for
readability. We no longer prefer this style of line splitting in the
driver, and new code is avoiding it.
Normally, I would leave this alone unless the actual function contents or
description needed updating. However, a future change is going to add
inverse functions for converting packed context to unpacked context
structures. To keep this code uniform with the existing set functions, fix
up the style to the modern format of keeping the type on the same line.

The functions used to pack the Tx and Rx context into the hardware format
rely on using BIT() and then subtracting 1 to get a bitmask. These
functions even have a comment about how x86 machines can't use this method
for certain widths because the SHL instructions will not work properly.
The Linux kernel already provides the GENMASK macro for generating a
suitable bitmask. Further, GENMASK is capable of generating the mask
including the shift_width. Since width is the total field width, take care
to subtract one to get the final bit position.
Since we now include the shifted bits as part of the mask, shift the source
value first before applying the mask.

In ice_common.c there are 4 functions used for converting the unpacked
software Tx and Rx context structure data into the packed format used by
hardware. These functions have extremely generic names:
* ice_write_byte
* ice_write_word
* ice_write_dword
* ice_write_qword
When I saw these function names my first thought was "write what? to
where?". Understanding what these functions do requires looking at the
implementation details. The functions take bits from an unpacked structure
and copy them into the packed layout used by hardware.
As part of live migration, we will want functions which perform the inverse
operation of reading bits from the packed layout and copying them into the
unpacked format. Naming these as "ice_read_byte", etc would be very
confusing since they appear to write data.
In preparation for adding this new inverse operation, rename the existing
functions to use the prefix "ice_pack_ctx_". This makes it clear that they
perform the bit packing while copying from the unpacked software context
structure to the packed hardware context.
The inverse operations can then neatly be named ice_unpack_ctx_*, clearly
indicating they perform the bit unpacking while copying from the packed
hardware context to the unpacked software context structure.

When initializing over virtchnl, the PF is required to pass a VSI ID to the
VF as part of its capabilities exchange. The VF driver reports this value
back to the PF in a variety of commands. The PF driver validates that this
value matches the value it sent to the VF.
Some hardware families such as the E700 series could use this value when
reading RSS registers or communicating directly with firmware over the
Admin Queue.
However, E800 series hardware does not support any of these interfaces and
the VF's only use for this value is to report it back to the PF. Thus,
there is no requirement that this value be an actual VSI ID value of any
kind.
The PF driver already does not trust that the VF sends it a real VSI ID.
The VSI structure is always looked up from the VF structure. The PF does
validate that the VSI ID provided matches a VSI associated with the VF, but
otherwise does not use the VSI ID for any purpose.
Instead of reporting the VSI number relative to the PF space, report a
fixed value of 1. When communicating with the VF over virtchnl, validate
that the VSI number is returned appropriately.
This avoids leaking information about the firmware of the PF state.
Currently the ice driver only supplies a VF with a single VSI. However, it
appears that virtchnl has some support for allowing multiple VSIs. I did
not attempt to implement this. However, space is left open to allow further
relative indexes if additional VSIs are provided in future feature
development. For this reason, keep the ice_vc_isvalid_vsi_id function in
place to allow extending it for multiple VSIs in the future.
This change will also simplify handling of live migration in a future
series. Since we no longer will provide a real VSI number to the VF, there
will be no need to keep track of this number when migrating to a new host.

The ice_vc_fdir_param_check() function validates that the VSI ID of the

already checked by the call to ice_vc_isvalid_vsi_id() immediately
following this.
This check is unnecessary since ice_vc_isvalid_vsi_id() already confirms
this by checking that the VSI ID can locate the VSI associated with the VF
structure.
Furthermore, a following change is going to refactor the ice driver to
report VSI IDs using a relative index for each VF instead of reporting the
PF VSI number. This additional check would break that logic since it
enforces that the VSI ID matches the VSI number.
Since this check duplicates the logic in ice_vc_isvalid_vsi_id() and gets
in the way of refactoring that logic, remove it.

The ice_vc_isvalid_q_id() function takes a VSI index and a queue ID. It
looks up the VSI from its index, and then validates that the queue number
is valid for that VSI.
The VSI ID passed is typically a VSI index from the VF. This VSI number is
validated by the PF to ensure that it matches the VSI associated with the
VF already.
In every flow where ice_vc_isvalid_q_id() is called, the PF driver already
has a pointer to the VSI associated with the VF. This pointer is obtained
using ice_get_vf_vsi(), rather than looking up the VSI using the index sent
by the VF.
Since we already know which VSI to operate on, we can modify
ice_vc_isvalid_q_id() to take a VSI pointer instead of a VSI index. Pass
the VSI we found from ice_get_vf_vsi() instead of re-doing the lookup. This
removes some unnecessary computation and scanning of the VSI list.
It also removes the last place where the driver directly used the VSI
number from the VF. This will pave the way for refactoring to communicate
relative VSI numbers to the VF instead of absolute numbers from the PF
space.

E800 series devices have a couple of quirks:
1. Sideband control queues are not supported
2. The registers that the driver needs to program for the "Precision

compared to other devices supported by this driver.
Both these require conditional logic based on the underlying device we
are dealing with.
The function ice_is_sbq_supported added by commit 8f5ee3c477
("ice: add support for sideband messages") addresses (1).
The same function can be used to address (2) as well
but this just looks weird readability wise in cases that have nothing
to do with sideband control queues:
if (ice_is_sbq_supported(hw))
/* program register A */
else
/* program register B */

The kernel build regressions/improvements email contained a couple of
issues with old compilers (in fact all the reports were on different
architectures, but all gcc 5.5) and the FIELD_PREP() and FIELD_GET()
conversions. They're all because an integer #define that should have
been declared as unsigned, was shifted to the point that it could set
the sign bit.
The fix just involves making sure the defines use the "U" identifier on
the constants to make sure they're unsigned. Should make the checkers
happier.
Confirmed with objdump before/after that there is no change to the
binaries.
Issues were reported as follows:
./drivers/net/ethernet/intel/ice/ice_base.c:238:7: note: in expansion of macro 'FIELD_GET'
(FIELD_GET(GLINT_CTL_ITR_GRAN_25_M, regval) == ICE_ITR_GRAN_US))

HW incorrectly reports EIPE errors on encapsulated packets
with L2 padding inside inner packet. HW shows outer UDP/IPV4
packet checksum errors as part of the EIPE flags of the
Rx descriptor. These are reported only if checksum offload
is enabled and L3/L4 parsed flag is valid in Rx descriptor.
When that error is reported by HW, we don't act on it
instead of incrementing main Rx errors statistic as it
would normally happen.
Add a new statistic to count these errors since we still want
to print them.
