[PATCH net-next v3 3/7] stmmac: intel: prepare to support 1000BASE-X phy interface setting

From: Ong Boon Leong
Date: Thu Jun 09 2022 - 23:41:08 EST


Currently, intel_speed_mode_2500() redundantly fix-up phy_interface to
PHY_INTERFACE_MODE_SGMII if the underlying controller is in 1000Mbps
SGMII mode. The value of phy_interface has been initialized earlier.

This patch removes such redundancy to prepare for setting 1000BASE-X
mode for certain hardware platform configuration.

Also update the intel_mgbe_common_data() to include 1000BASE-X setup.
