igc: Fix ambiguity in the ethtool advertising

Browse source

[ Upstream commit e7684d29ef ]

The 'ethtool_convert_link_mode_to_legacy_u32' method does not allow us to
advertise 2500M speed support and TP (twisted pair) properly. Convert to
'ethtool_link_ksettings_test_link_mode' to advertise supported speed and
eliminate ambiguity.
