[PATCH net-next RFC v2 3/6] net: ethtool: Export the link_mode_params definitions

[Maxime Chevallier <maxime.chevallier@xxxxxxxxxxx>]

link_mode_params contains a lookup table of all 802.3 link modes that
are currently supported with structured data about each mode's speed,
duplex, number of lanes and mediums.

As a preparation for a port representation, export that table for the
rest of the net stack to use.
