Subject: [PATCH] net/mlx5: ethtool, Fix type analysis of advertised link-mode
Ethtool option set_link_ksettings allows setting of legacy link-modes
or extended link-modes. Refine the decision of which type of link-modes
is set.
Fixes: 6a897372417e ("net/mlx5: ethtool, Add ethtool support for 50Gbps per lane link modes")
