Therefore, remove the mac_port_config member from ID_MT7988 in mt753x_table. Before calling priv->info->mac_port_config(), if there's no mac_port_config member in mt753x_table, exit mt753x_mac_config() successfully. Remove calling priv->info->mac_port_config() from the sanity check as the sanity check requires a pointer to a mac_port_config function to be non-NULL. This will fail for MT7988 as mac_port_config won't be a member of its info table.

It sets up the ports described as a CPU port earlier than the phylink code path would do. This function is useless as: - Configuring the MACs can be done from the phylink_mac_config code path instead. - All the link configuration it does on the CPU ports are later undone with the port_enable, phylink_mac_config, and then phylink_mac_link_up code path [1]. priv->p5_interface and priv->p6_interface were being used to prevent configuring the MACs from the phylink_mac_config code path. Remove them now that they hold no purpose. Remove priv->info->cpu_port_config(). On mt753x_phylink_mac_config, switch to if statements to simplify the code. Remove the overwriting of the speed and duplex interfaces for certain interface modes. Phylink already provides the speed and duplex variables with proper values. Phylink already sets the max speed of TRGMII to SPEED_1000. Add SPEED_2500 for PHY_INTERFACE_MODE_2500BASEX to where the speed and EEE bits are set instead. On the switch on the MT7988 SoC, PHY_INTERFACE_MODE_INTERNAL is being used to describe the interface mode of the 10G MAC, which is of port 6. On mt7988_cpu_port_config() PMCR_FORCE_SPEED_1000 was set via the PMCR_CPU_PORT_SETTING() mask. Add SPEED_10000 case to where the speed bits are set to cover this. No need to add it to where the EEE bits are set as the "MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open Version) v0.1" document shows that these bits don't exist on the MT7530_PMCR_P(6) register. Remove the definition of PMCR_CPU_PORT_SETTING() now that it holds no purpose. Change mt753x_cpu_port_enable() to void now that there're no error cases left.

Move that to mt7530_setup() and mt7531_setup_common() which set up the switches. This way, the link settings are cleared on all ports at setup, and then only once with phylink_mac_link_down() when a link goes down. Enable force mode at setup to apply the force part of the link settings. This ensures that disabled ports will have their link down.

The bit for setting the port on force mode is already done on mt7530_setup() and mt7531_setup_common(). So get rid of PMCR_FORCE_MODE_ID() which helped determine which bit to use for the switch model.
