Support querying and resetting to default param values.
Introduce two new devlink netlink attrs:
DEVLINK_ATTR_PARAM_VALUE_DEFAULT and
DEVLINK_ATTR_PARAM_RESET_DEFAULT. The former is used to contain an
optional parameter value inside of the param_value nested
attribute. The latter is used in param-set requests from userspace to
indicate that the driver should reset the param to its default value.
To implement this, two new functions are added to the devlink driver
api: devlink_param::get_default() and
devlink_param::reset_default(). These callbacks allow drivers to
implement default param actions for runtime and permanent cmodes. For
driverinit params, the core latches the last value set by a driver via
devl_param_driverinit_value_set(), and uses that as the default value
for a param.
Because default parameter values are optional, it would be impossible
to discern whether or not a param of type bool has default value of
false or not provided if the default value is encoded using a netlink
flag type. For this reason, when a DEVLINK_PARAM_TYPE_BOOL has an
associated default value, the default value is encoded using a u8
type.

Adds DEVLINK_ESWITCH_MODE_SWITCHDEV_INACTIVE attribute to UAPI and
documentation.
Before having traffic flow through an eswitch, a user may want to have the
ability to block traffic towards the FDB until FDB is fully programmed and
the user is ready to send traffic to it. For example: when two eswitches
are present for vports in a multi-PF setup, one eswitch may take over the
traffic from the other when the user chooses.
Before this take over, a user may want to first program the inactive
eswitch and then once ready redirect traffic to this new eswitch.
switchdev modes transition semantics:
legacy->switchdev_inactive: Create switchdev mode normally, traffic not
allowed to flow yet.
switchdev_inactive->switchdev: Enable traffic to flow.
switchdev->switchdev_inactive: Block traffic on the FDB, FDB and
representros state and content is preserved.
When eswitch is configured to this mode, traffic is ignored/dropped on
this eswitch FDB, while current configuration is kept, e.g FDB rules and
netdev representros are kept available, FDB programming is allowed.
Example:
# start inactive switchdev
devlink dev eswitch set pci/0000:08:00.1 mode switchdev_inactive
# setup TC rules, representors etc ..
# activate
devlink dev eswitch set pci/0000:08:00.1 mode switchdev

Enable configuration of the burst period — a time window starting
from the first error recovery, during which the reporter allows
recovery attempts for each reported error.
This feature is helpful when a single underlying issue causes multiple
errors, as it delays the start of the grace period to allow sufficient
time for recovering all related errors. For example, if multiple TX
queues time out simultaneously, a sufficient burst period could allow
all affected TX queues to be recovered within that window. Without this
period, only the first TX queue that reports a timeout will undergo
recovery, while the remaining TX queues will be blocked once the grace
period begins.
Configuration example:
$ devlink health set pci/0000:00:09.0 reporter tx burst_period 500
Configuration example with ynl:
./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/devlink.yaml \
--do health-reporter-set --json '{

The devlink_nl_rate_tc_bw_parse function uses a large stack array for
devlink attributes, which triggers a warning about excessive stack
usage:
net/devlink/rate.c: In function 'devlink_nl_rate_tc_bw_parse':
net/devlink/rate.c:382:1: error: the frame size of 1648 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
Introduce a separate attribute set specifically for rate TC bandwidth
parsing that only contains the two attributes actually used: index
and bandwidth. This reduces the stack array from DEVLINK_ATTR_MAX
entries to just 2 entries, solving the stack usage issue.
Update devlink selftest to use the new 'index' and 'bw' attribute names
consistent with the YAML spec.
Example usage with ynl with the new spec:

Introduce support for specifying relative bandwidth shares between
traffic classes (TC) in the devlink-rate API. This new option allows
users to allocate bandwidth across multiple traffic classes in a
single command.
This feature provides a more granular control over traffic management,
especially for scenarios requiring Enhanced Transmission Selection.
Users can now define a relative bandwidth share for each traffic class.
For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5
(RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the
total bandwidth. The actual percentage each class receives depends on
the ratio of its share value to the sum of all shares.
Example:
DEV=pci/0000:08:00.0
$ devlink port function rate add $DEV/vfs_group tx_share 10Gbit \
tx_max 50Gbit tc-bw 0:20 1:0 2:0 3:0 4:0 5:80 6:0 7:0
$ devlink port function rate set $DEV/vfs_group \
tc-bw 0:20 1:0 2:0 3:0 4:0 5:20 6:60 7:0
Example usage with ynl:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \
--do rate-set --json '{
"bus-name": "pci",

Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special

Devlink param and health reporter fmsg use attributes with dynamic type
which is determined according to a different type. Currently used values
are NLA_*. The problem is, they are not part of UAPI. They may change
which would cause a break.
To make this future safe, introduce a enum that shadows NLA_* values in
it and is part of UAPI.
Also, this allows to possibly carry types that are unrelated to NLA_*
values.

Device drivers register with devlink from their probe routines (under
the device lock) by acquiring the devlink instance lock and calling
devl_register().
Drivers that support a devlink reload usually implement the
reload_{down, up}() operations in a similar fashion to their remove and
probe routines, respectively.
However, while the remove and probe routines are invoked with the device
lock held, the reload operations are only invoked with the devlink
instance lock held. It is therefore impossible for drivers to acquire
the device lock from their reload operations, as this would result in
lock inversion.
The motivating use case for invoking the reload operations with the
device lock held is in mlxsw which needs to trigger a PCI reset as part
of the reload. The driver cannot call pci_reset_function() as this
function acquires the device lock. Instead, it needs to call
__pci_reset_function_locked which expects the device lock to be held.
To that end, adjust devlink to always acquire the device lock before the
devlink instance lock when performing a reload.
Do that when reload is explicitly triggered by user space by specifying
the 'DEVLINK_NL_FLAG_NEED_DEV_LOCK' flag in the pre_doit and post_doit
operations of the reload command.
A previous patch already handled the case where reload is invoked as
part of netns dismantle.

Python YNL is much more forgiving than the C code gen in terms
of the spec completeness. Fill in a handful of devlink details
to make the spec usable in C.

Devlink is quite complex but put in the very basics so we can
incrementally fill in the commands as needed.
$ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \
--dump get
[{'bus-name': 'netdevsim',
'dev-name': 'netdevsim1',
'dev-stats': {'reload-stats': {'reload-action-info': {'reload-action': 1,
'reload-action-stats': {'reload-stats-entry': [{'reload-stats-limit': 0,
'reload-stats-value': 0}]}}},
'remote-reload-stats': {'reload-action-info': {'reload-action': 2,
'reload-action-stats': {'reload-stats-entry': [{'reload-stats-limit': 0,
'reload-stats-value': 0},
{'reload-stats-limit': 1,
'reload-stats-value': 0}]}}}},
