Date: Mon, 7 Feb 2022 11:12:31 +0200 From: Danielle Ratson <danieller@...dia.com> To: <netdev@...r.kernel.org> CC: <mkubecek@...e.cz>, <vadimp@...dia.com>, <mlxsw@...dia.com>, "Danielle Ratson" <danieller@...dia.com> Subject: [PATCH ethtool-next] ethtool: Add support for OSFP transceiver modules OSFP transceiver modules use the same management interface specification (CMIS) as QSFP-DD and DSFP modules. Allow ethtool to dump, parse and print their EEPROM contents by adding their SFF-8024 Identifier Value (0x19). This is required for future NVIDIA Spectrum-4 based systems that will be equipped with OSFP transceivers. While at it, add the DSFP identifier to the IOCTL path, as it was missing.
