Subject: [PATCH] net: ethernet: mvneta: Do not error out in non serdes modes
In mvneta_config_interface() the RGMII modes are catched by the default
case which is an error return. The RGMII modes are valid modes for the
driver, so instead of returning an error add a break statement to return
successfully.
This avoids this warning for non comphy SoCs which use RGMII, like
SolidRun Clearfog:
WARNING: CPU: 0 PID: 268 at drivers/net/ethernet/marvell/mvneta.c:3512 mvneta_start_dev+0x220/0x23c
