From: Shahar Shitrit <shshitrit@nvidia.com>

The function ptys2ethtool_adver_link() contains duplicated code that
is found in mlx5e_ethtool_get_speed_arr().

To eliminate this redundancy, we update mlx5e_ethtool_get_speed_arr()
to select the appropriate table based on the ext argument passed by
the caller, rather than querying the supported mode locally.

This allows us to replace the current logic in ptys2ethtool_adver_link()
with a call to mlx5e_ethtool_get_speed_arr().

This adjustment aligns with the ptys2ethtool_supported_link() function
and prepares for an upcoming patch that reduces code duplication.
