Subject: [PATCH net-next v3 1/7] net: ethtool: pse-pd: Expand C33 PSE
status with class, power and extended state
From: Kory Maincent (Dent Project) <kory.maincent@...tlin.com>
This update expands the status information provided by ethtool for PSE c33.
It includes details such as the detected class, current power delivered,
and extended state information.
Signed-off-by: Kory Maincent <kory.maincent@...tlin.com>
---
Change in v2:
- Move on PSE string error messages to ETHTOOL_LINK_EXT_STATE and
ETHTOOL_LINK_EXT_SUBSTATE with fixed enumeration in aim to unify
interface diagnostic.
Change in v3:
- Add ethtool netlink documentation and kdoc.
- Move on to u32 for state and substate.
- Update C33 pse extended state and substate following Oleksij proposal
