Subject: [PATCH net-next 4/8] net/mlx5: Add support for DSFP module EEPROM dumps

From: Moshe Shemesh <[email-masked]>
Date: Fri, 9 Apr 2021 11:06:37 +0300

From: Vladyslav Tarasiuk <[email-masked]>

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