When both supported and previous version have the same major version,
and the firmwares are missing, the driver ends in a loop requesting the
same (previous) version over and over again:
[ 76.327413] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.1.img firmware, fall-back to previous 4.0 version

...
Fix this by inverting the check to that we aren't yet at the previous
version, and also check the minor version.
This also catches the case where both versions are the same, as it was
after commit bb5dbf2cc6 ("net: marvell: prestera: add firmware v4.0
support").
With this fix applied:
[ 88.499622] Prestera DX 0000:01:00.0: missing latest mrvl/prestera/mvsw_prestera_fw-v4.1.img firmware, fall-back to previous 4.0 version
[ 88.511995] Prestera DX 0000:01:00.0: failed to request previous firmware: mrvl/prestera/mvsw_prestera_fw-v4.0.img

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Adjust drivers that support the 'FLOW_DISSECTOR_KEY_META' key to reject
filters that try to match on the newly added layer 2 miss field. Add an
extack message to clearly communicate the failure reason to user space.
The following users were not patched:
1. mtk_flow_offload_replace(): Only checks that the key is present, but
does not do anything with it.
2. mlx5_tc_ct_set_tuple_match(): Used as part of netfilter offload,
which does not make use of the new field, unlike tc.
3. get_netdev_from_rule() in nfp: Likewise.
Example:
# tc filter add dev swp1 egress pref 1 proto all flower skip_sw l2_miss true action drop

The driver name is available in device_driver::name. Right now,
drivers still have to report this piece of information themselves in
their devlink_ops::info_get callback function.
In order to factorize code, make devlink_nl_info_fill() add the driver
name attribute.
Now that the core sets the driver name attribute, drivers are not
supposed to call devlink_info_driver_name_put() anymore. Remove
devlink_info_driver_name_put() and clean-up all the drivers using this
function in their callback.

This driver fist makes an expensive DT lookup to retrieve its DT node
(this is a PCI driver) in order to later search for the
base-mac-provider property. This property has no reality upstream and
this code should not have been accepted like this in the first
place. Instead, there is a proper nvmem interface that should be
used. Let's avoid these extra lookups and rely on the nvmem internal

Virtually all conventional network drivers are now converted to use
phylink_generic_validate() - only DSA drivers and fman_memac remain,
so lets remove the necessity for network drivers to explicitly set
this member, and default to phylink_generic_validate() when unset.
This is possible as .validate must currently be set.
Any remaining instances that have not been addressed by this patch can
be fixed up later.

If you try to create a 'mirror' ACL rule on a port that already has a
mirror rule, prestera_span_rule_add() will fail with EEXIST error.
This forces rollback procedure which destroys existing mirror rule on

Add an explicit check for EEXIST to prevent the deletion of the existing
rule but keep user seeing error message:

We poll nexthops in HW and call for each active nexthop appropriate
neighbour.
Also we provide implicity neighbour resolving.
For example, user have added nexthop route:
# ip route add 5.5.5.5 via 1.1.1.2
But neighbour 1.1.1.2 doesn't exist. In this case we will try to call
neigh_event_send, even if there is no traffic.
This is useful, when you have add route, which will be used after some
time but with a lot of traffic (burst). So, we has prepared, offloaded
route in advance.

matchall rules can be added only to chain 0 and their priorities have
limitations:
- new matchall ingress rule's priority must be higher (lower value)
than any existing flower rule;
- new matchall egress rule's priority must be lower (higher value)
than any existing flower rule.
The opposite works for flower rule adding:
- new flower ingress rule's priority must be lower (higher value)
than any existing matchall rule;
- new flower egress rule's priority must be higher (lower value)
than any existing matchall rule.
This is a hardware limitation and thus must be properly handled in
driver by reporting errors to the user when newly added rule has such a
priority that cannot be installed into the hardware.
To achieve this, the driver must maintain both min/max matchall
priorities for every flower block when user adds/deletes a matchall
rule, as well as both min/max flower priorities for chain 0 for every
adding/deletion of flower rules for chain 0.
