Subject: [PATCH net-next 02/15] ice: rework of dump serdes equalizer values feature
From: Mateusz Polchlopek <mateusz.polchlopek@...el.com>
Refactor function ice_get_tx_rx_equa() to iterate over new table of
params instead of multiple calls to ice_aq_get_phy_equalization().
Subsequent commit will extend that function by add more serdes equalizer
values to dump.
Shorten the fields of struct ice_serdes_equalization_to_ethtool for
readability purposes.
