net/mlx5e: Use the correct pause values for ethtool advertising
Query the operational pause from firmware (PFCC register) instead of always passing zeros. Fixes: 665bc53969d7 ("net/mlx5e: Use new ethtool get/set link ksettings API") Signed-off-by: Gal Pressman <galp@mellanox.com> Cc: kernel-team@fb.com Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
