Subject: [PATCH net-next 12/12] mlxsw: core: Add support for OSFP transceiver modules
Date: Tue, 22 Feb 2022 19:17:03 +0200 [thread overview]
Message-ID: <20220222171703.499645-13-idosch@nvidia.com> (raw)
In-Reply-To: <20220222171703.499645-1-idosch@nvidia.com>
From: Danielle Ratson <danieller@nvidia.com>
The driver can already dump the EEPROM contents of QSFP-DD transceiver
modules via its ethtool_ops::get_module_info() and
ethtool_ops::get_module_eeprom() callbacks.
Add support for OSFP transceiver modules 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.
