Subject: [PATCH net-next 4/8] net/mlx5: Add support for DSFP module EEPROM dumps
Date: Fri, 9 Apr 2021 11:06:37 +0300 [thread overview]
Message-ID: <1617955601-21055-5-git-send-email-moshe@nvidia.com> (raw)
In-Reply-To: <1617955601-21055-1-git-send-email-moshe@nvidia.com>
From: Vladyslav Tarasiuk <vladyslavt@nvidia•com>
Allow the driver to recognise DSFP transceiver module ID and therefore
allow its EEPROM dumps using ethtool.
Signed-off-by: Vladyslav Tarasiuk <vladyslavt@nvidia•com>
