4cddb0f15e net: ethtool: pse-pd: Fix possible null-deref
Fix a possible null dereference when a PSE supports both c33 and PoDL, but
only one of the netlink attributes is specified. The c33 or PoDL PSE
capabilities are already validated in the ethnl_set_pse_validate() call.

93c3a96c30 net: pse-pd: Do not return EOPNOSUPP if config is null
For a PSE supporting both c33 and PoDL, setting config for one type of PoE
leaves the other type's config null. Currently, this case returns
EOPNOTSUPP, which is incorrect. Instead, we should do nothing if the
configuration is empty.

30d7b67277 net: ethtool: Add new power limit get and set features
This patch expands the status information provided by ethtool for PSE c33
with available power limit and available power limit ranges. It also adds
a call to pse_ethtool_set_pw_limit() to configure the PSE control power
limit.

b010bf72da net: pse-pd: Rectify and adapt the naming of admin_cotrol member of struct pse_control_config
In commit 18ff0bcda6 ("ethtool: add interface to interact with Ethernet
Power Equipment"), the 'pse_control_config' structure was introduced,
housing a single member labeled 'admin_cotrol' responsible for maintaining
the operational state of the PoDL PSE functions.

A noticeable typographical error exists in the naming of this field
('cotrol' should be corrected to 'control'), which this commit aims to
rectify.

Furthermore, with upcoming extensions of this structure to encompass PoE
functionalities, the field is being renamed to 'podl_admin_state' to
distinctly indicate that this state is tailored specifically for PoDL."

f946270d05 ethtool: netlink: always pass genl_info to .prepare_data
We had a number of bugs in the past because developers forgot
to fully test dumps, which pass NULL as info to .prepare_data.
.prepare_data implementations would try to access info->extack
leading to a null-deref.

Now that dumps and notifications can access struct genl_info
we can pass it in, and remove the info null checks.

46cdedf2a0 ethtool: pse-pd: fix null-deref on genl_info in dump
ethnl_default_dump_one() passes NULL as info.

It's correct not to set extack during dump, as we should just
silently skip interfaces which can't provide the information.

18ff0bcda6 ethtool: add interface to interact with Ethernet Power Equipment
Add interface to support Power Sourcing Equipment. At current step it
provides generic way to address all variants of PSE devices as defined
in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4
PoDL Power Sourcing Equipment (PSE).

Currently supported and mandatory objects are:
IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus
IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState
IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl

This is minimal interface needed to control PSE on each separate
ethernet port but it provides not all mandatory objects specified in
IEEE 802.3-2018.

Since "PoDL PSE" and "PSE" have similar names, but some different values
I decide to not merge them and keep separate naming schema. This should
allow as to be as close to IEEE 802.3 spec as possible and avoid name
conflicts in the future.

This implementation is connected to PHYs instead of MACs because PSE
auto classification can potentially interfere with PHY auto negotiation.
So, may be some extra PHY related initialization will be needed.

With WIP version of ethtools interaction with PSE capable link looks
as following:

$ ip l
...
5: t1l1@eth0: <BROADCAST,MULTICAST> ..
...

$ ethtool --show-pse t1l1
PSE attributs for t1l1:
PoDL PSE Admin State: disabled
PoDL PSE Power Detection Status: disabled

$ ethtool --set-pse t1l1 podl-pse-admin-control enable
$ ethtool --show-pse t1l1
PSE attributs for t1l1:
PoDL PSE Admin State: enabled
PoDL PSE Power Detection Status: delivering power
