Subject: [PATCH net-next v4 2/5] stmmac: intel: prepare to support 1000BASE-X phy interface setting
Date:   Tue, 14 Jun 2022 11:00:27 +0800
Message-Id: <20220614030030.1249850-3-boon.leong.ong@intel.com>

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.
