ethtool: Expand Ethernet Power Equipment with c33 (PoE) alongside PoDL
In the current PSE interface for Ethernet Power Equipment, support is
limited to PoDL. This patch extends the interface to accommodate the
objects specified in IEEE 802.3-2022 145.2 for Power sourcing
Equipment (PSE).
The following objects are now supported and considered mandatory:
- IEEE 802.3-2022 30.9.1.1.5 aPSEPowerDetectionStatus
- IEEE 802.3-2022 30.9.1.1.2 aPSEAdminState
- IEEE 802.3-2022 30.9.1.2.1 aPSEAdminControl
To avoid confusion between "PoDL PSE" and "PoE PSE", which have similar
names but distinct values, we have followed the suggestion of Oleksij
Rempel and Andrew Lunn to maintain separate naming schemes for each,
using c33 (clause 33) prefix for "PoE PSE".
