[RFC PATCH V5 net-next 4/5] net/mlx5: Add support for DSFP module EEPROM dumps

From: Moshe Shemesh <hidden>
Date: 2021-03-25 14:58:04
Subsystem: mellanox mlx5 ib driver, mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers: Leon Romanovsky, Saeed Mahameed, Tariq Toukan, Mark Bloch, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Vladyslav Tarasiuk <redacted>

Allow the driver to recognise DSFP transceiver module ID and therefore
allow its EEPROM dumps using ethtool.
