   4 Subject: [PATCH] net: mtk_eth_soc: remove interface checks in mtk_validate()
   5
   6 As phylink checks the interface mode against the supported_interfaces
   7 bitmap, we no longer need to validate the interface mode, nor handle
   8 PHY_INTERFACE_MODE_NA in the validation function. Remove these to
   9 simplify the implementation.
