sopass won't be set if wolopt doesn't change. This means the following
will fail to set the correct sopass.
ethtool -s eth0 wol s sopass 11:22:33:44:55:66
ethtool -s eth0 wol s sopass 22:44:55:66:77:88
Make sure we call into the driver layer set_wol if sopass is different.

Instead of reimplementing policies in MutliAttr for every
underlying type forward the calls to the base type.
This will be needed for DPLL which uses a multi-attr nest,
and currently gets an invalid NLA_NEST policy generated.

RVU NIX AF driver updates
This patch series includes a few enhancements and other updates to the
RVU NIX AF driver.
The first patch adds devlink option to configure NPC MCAM high priority
zone entries reservation. This is useful when the requester needs more
high priority entries than default reserved entries.
The second patch adds support for RSS hash computation using L3 SRC or
DST only, or L4 SRC or DST only.
The third patch updates DWRR MTU configuration for CN10KB silicon. HW uses
the DWRR MTU to compute DWRR weight.
Patch 4 configures the LBK link in TL3_TL2 configuration only when switch
mode is enabled.
Patch 5 adds an option in the mailbox request to enable/disable DROP_RE bit
which drops packets with L2 errors when set.
Patch 6 updates SMQ flush mechanism to stop other child nodes from
enqueuing any packets while SMQ flush is active. Otherwise SMQ flush may
timeout.

When multiple transmit scheduler queues feed a TL1 transmit link, the
SMQ flush initiated on a low priority queue might get stuck when a high
priority queue fully subscribes the transmit link. This inturn effects
interface teardown. To avoid this, temporarily XOFF all TL1's other
immediate child transmit scheduler queues and also clear any rate limit
configuration on all the scheduler queues in SMQ(flush) hierarchy.

The DWRR MTU config added for SDP and RPM/LBK links on CN10K
silicon is further extended on CK10KB silicon variant and made
it configurable. Now there are 4 DWRR MTU config to choose while
setting transmit scheduler's RR_WEIGHT.
Here we are reserving one config for each of RPM, SDP and LBK.
NIXX_AF_DWRR_MTUX(0) ---> RPM
NIXX_AF_DWRR_MTUX(1) ---> SDP
NIXX_AF_DWRR_MTUX(2) ---> LBK
PF/VF drivers can choose the DWRR_MTU to be used by setting
SMQX_CFG[pkt_link_type] to one of above. TLx_SCHEDULE[RR_WEIGHT]
is to be as configured 'quantum / 2^DWRR_MTUX[MTU]'. DWRR_MTU
of each link is exposed to PF/VF drivers via mailbox for
RR_WEIGHT calculation.

Add support to select L3 SRC or DST only, L4 SRC or DST only for RSS
calculation.
AF consumer may have requirement as we can select only SRC or DST data for
RSS calculation in L3, L4 layers. With this requirement there will be
following combinations, IPV[4,6]_SRC_ONLY, IPV[4,6]_DST_ONLY,
[TCP,UDP,SCTP]_SRC_ONLY, [TCP,UDP,SCTP]_DST_ONLY. So, instead of creating
a bit for each combination, we are using upper 4 bits (31:28) in the
flow_key_cfg to represent the SRC, DST selection. 31 => L3_SRC,
30 => L3_DST, 29 => L4_SRC, 28 => L4_DST. These won't be part of flow_cfg,
so that we don't need to change the existing ABI.

The NPC MCAM entries are currently divided into three priority zones
in AF driver: high, mid, and low. The high priority zone and low priority
zone take up 1/8th (each) of the available MCAM entries, and remaining
going to the mid priority zone.
The current allocation scheme may not meet certain requirements, such
as when a requester needs more high priority zone entries than are
reserved. This patch adds a devlink configurable option to increase the
number of high priority zone entries that can be allocated by requester.
The max number of entries that can be reserved for high priority usage
is 100% of available MCAM entries.
Usage:
1) Change high priority zone percentage to 75%:
devlink -p dev param set pci/0002:01:00.0 name npc_mcam_high_zone_percent \
value 75 cmode runtime
2) Read high priority zone percentage:
devlink -p dev param show pci/0002:01:00.0 name npc_mcam_high_zone_percent
The devlink set configuration is only permitted when no MCAM entries
are assigned, i.e., all MCAM entries are free, indicating that no PF/VF
driver is loaded. So user must unload/unbind PF/VF driver/devices before
modifying the high priority zone percentage.

(2) Remove hash_sendpage*() from AF_ALG.
(3) Make sunrpc send multiple pages in single sendmsg() call rather than
calling sendpage() in TCP (or maybe TLS).

Rewrite the AF_KCM transmission loop to send all the fragments in a single
skb or frag_list-skb in one sendmsg() with MSG_SPLICE_PAGES set. The list
of fragments in each skb is conveniently a bio_vec[] that can just be
attached to a BVEC iter.
Note: I'm working out the size of each fragment-skb by adding up bv_len for
all the bio_vecs in skb->frags[] - but surely this information is recorded
somewhere? For the skbs in head->frag_list, this is equal to
skb->data_len, but not for the head. head->data_len includes all the tail
frags too.

1) Embedded CPU Virtual Functions
2) Lightweight local SFs
Daniel Jurgens says:
====================
Embedded CPU Virtual Functions
This series enables the creation of virtual functions on Bluefield (the
embedded CPU platform). Embedded CPU virtual functions (EC VFs). EC VF
creation, deletion and management interfaces are the same as those for
virtual functions in a server with a Connect-X NIC.
When using EC VFs on the ARM the creation of virtual functions on the
host system is still supported. Host VFs eswitch vports occupy a range
of 1..max_vfs, the EC VF vport range is max_vfs+1..max_ec_vfs.
Every function (PF, ECPF, VF, EC VF, and subfunction) has a function ID
associated with it. Prior to this series the function ID and the eswitch
vport were the same. That is no longer the case, the EC VF function ID
range is 1..max_ec_vfs. When querying or setting the capabilities of an
EC VF function an new bit must be set in the query/set HCA cap
structure.
This is a high level overview of the changes made:
- Allocate vports for EC VFs if they are enabled.
- Create representors and devlink ports for the EC VF vports.
- When querying/setting HCA caps by vport break the assumption
that function ID is the same a vport number and adjust
accordingly.
- Create a new type of page, so that when SRIOV on the ARM is
disabled, but remains enabled on the host, the driver can
wait for the correct pages.
- Update SRIOV code to support EC VF creation/deletion.
===================
Lightweight local SFs:
Last 3 patches form Shay Drory:
SFs are heavy weight and by default they come with the full package of
ConnectX features. Usually users want specialized SFs for one specific
purpose and using devlink users will almost always override the set of
advertises features of an SF and reload it.
Shay Drory says:
================
In order to avoid the wasted time and resources on the reload, local SFs
will probe without any auxiliary sub-device, so that the SFs can be
configured prior to its full probe.
The defaults of the enable_* devlink params of these SFs are set to
false.
Usage example:
Create SF:
$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11
$ devlink port function set pci/0000:08:00.0/32768 \
hw_addr 00:00:00:00:00:11 state active
Enable ETH auxiliary device:
$ devlink dev param set auxiliary/mlx5_core.sf.1 \
name enable_eth value true cmode driverinit
Now, in order to fully probe the SF, use devlink reload:
$ devlink dev reload auxiliary/mlx5_core.sf.1
At this point the user have SF devlink instance with auxiliary device
for the Ethernet functionality only.

Commit 4a19edb60d02 ("netlink: Pass extack to dump handlers")
added extack support to netlink dumps. It was focused on rtnl
and since rtnl does not use ->start(), ->done() callbacks
it ignored those. Genetlink on the other hand uses ->start()
extensively, for parsing and input validation.
Pass the extact in via struct netlink_dump_control and link
it to cb for the time of ->start(). Both struct netlink_dump_control
and extack itself live on the stack so we can't keep the same
extack for the duration of the dump. This means that the extack
visible in ->start() and each ->dump() callbacks will be different.
Corner cases like reporting a warning message in DONE across dump
calls are still not supported.
We could put the extack (for dumps) in the socket struct,
but layering makes it slightly awkward (extack pointer is decided
before the DO / DUMP split).
The genetlink dump error extacks are now surfaced:
$ cli.py --spec netlink/specs/ethtool.yaml --dump channels-get
lib.ynl.NlError: Netlink error: Invalid argument
nl_len = 64 (48) nl_flags = 0x300 nl_type = 2
error: -22 extack: {'msg': 'request header missing'}
Previously extack was missing:
$ cli.py --spec netlink/specs/ethtool.yaml --dump channels-get
lib.ynl.NlError: Netlink error: Invalid argument
nl_len = 36 (20) nl_flags = 0x100 nl_type = 2

tools: ynl: generate code for the ethtool family
And finally ethtool support. Thanks to Stan's work the ethtool family
spec is quite complete, so there is a lot of operations to support.
I chickened out of stats-get support, they require at the very least
type-value support on a u64 scalar. Type-value is an arrangement where
a u16 attribute is encoded directly in attribute type. Code gen can
support this if the inside is a nest, we just throw in an extra
field into that nest to carry the attr type. But a little more coding
is needed to for a scalar, because first we need to turn the scalar
into a struct with one member, then we can add the attr type.
Other than that ethtool required event support (notification which
does not share contents with any GET), but the previous series
already added that to the codegen.
I haven't tested all the ops here, and a few I tried seem to work.

Since enum ethtool_stringset exists in the uAPI we need to include
at least a stub of it in the spec. This will trigger name collision
avoidance in the code gen.

Ethtool has an attribute set called stringset, from which
we'll generate struct ethtool_stringset. Unfortunately,
the old ethtool header declares enum ethtool_stringset
(the same name), to which compilers object.
This seems unavoidable. Check struct names against known
constants and append an underscore if conflict is detected.

If attr set or enum has empty enum name we need to use u32 or int
as function arguments and struct members.

Most of the C enum names are guessed correctly, but there
is a handful of corner cases we need to name explicitly.

Ethtool's PSE PoDL has a attr nest with different prefixes:
/* Power Sourcing Equipment */
enum {
ETHTOOL_A_PSE_UNSPEC,
ETHTOOL_A_PSE_HEADER, /* nest - _A_HEADER_* */
ETHTOOL_A_PODL_PSE_ADMIN_STATE, /* u32 */
ETHTOOL_A_PODL_PSE_ADMIN_CONTROL, /* u32 */
ETHTOOL_A_PODL_PSE_PW_D_STATUS, /* u32 */
Header has a prefix of ETHTOOL_A_PSE_ and other attrs prefix of
ETHTOOL_A_PODL_PSE_ we can't cover them uniformly.
If PODL was after PSE life would be easy.
Now we either need to add prefixes to attr names which is yucky
or support setting prefix name per attr.

ynl-regen needs to know the arguments used to generate a file.
Record excluded ops and, while at it, user headers.

The ethtool family has a small handful of quite tricky ops
and a lot of simple very useful ops. Teach ynl-gen to skip
ops so that we can bypass the tricky ones.
