   4 Subject: [PATCH 097/250] net: ethernet: mtk_eth_soc: remove mac_pcs_get_state
   5  and modernise
   6
   7 Remove the .mac_pcs_get_state function, since as far as I can tell is
   8 never called - no DT appears to specify an in-band-status management
   9 nor SFP support for this driver.
  10
  11 Removal of this, along with the previous patch to remove the incorrect
  12 clocking configuration, means that the driver becomes non-legacy, so
  13 we can remove the "legacy_pre_march2020" status from this driver.
