net/mlx5e: ethtool, Remove unsupported SFP EEPROM high pages query
Querying EEPROM high pages data for SFP module is currently not supported by our driver and yet queried, resulting in invalid FW queries. Set the EEPROM ethtool data length to 256 for SFP module will limit the reading for page 0 only and prevent invalid FW queries. Fixes: bb64143eee8c ("net/mlx5e: Add ethtool support for dump module EEPROM") Signed-off-by: Erez Alfasi <ereza@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
