Subject: [PATCH net-next v2 1/3] ethtool: Add new result codes for TDR diagnostics
Date: Thu, 8 Aug 2024 15:08:31 +0200 [thread overview]
Message-ID: <20240808130833.2083875-1-o.rempel@pengutronix.de> (raw)
Add new result codes to support TDR diagnostics in preparation for
Open Alliance 1000BaseT1 TDR support:
- ETHTOOL_A_CABLE_RESULT_CODE_NOISE: TDR not possible due to high noise
level.
- ETHTOOL_A_CABLE_RESULT_CODE_RESOLUTION_NOT_POSSIBLE: TDR resolution not
possible / out of distance.
