What makes priv->p5_interface and priv->p6_interface useless for MT7530
as you say? This code in mt753x_phylink_mac_config() seems executed
regardless of switch family:

	case 5:
		if (priv->p5_interface == state->interface)
			break;

		if (mt753x_mac_config(ds, port, mode, state) < 0)
			goto unsupported;

		if (priv->p5_intf_sel != P5_DISABLED)
			priv->p5_interface = state->interface;
		break;
	case 6:
		if (priv->p6_interface == state->interface)
			break;

		mt753x_pad_setup(ds, state);

		if (mt753x_mac_config(ds, port, mode, state) < 0)
			goto unsupported;

		priv->p6_interface = state->interface;
		break;
