    drivers: net: cpsw: fix RMII/RGMII mode when used with fixed-link PHY · f1eea5c1
    David Rivshin authored
    Commit 1f71e8c9 ("drivers: net: cpsw: Add
    support for fixed-link PHY") did not parse the "phy-mode" property in
    the case of a fixed-link PHY, leaving slave_data->phy_if with its default
    of PHY_INTERFACE_MODE_NA(0). This later gets passed to phy_connect() in
    cpsw_slave_open(), and eventually to cpsw_phy_sel() where it hits a default
    case that configures the MAC for MII mode.
    
    The user visible symptom is that while kernel log messages seem to indicate
    that the interface is set up, there is no network communication. Eventually
    a watchdog error occurs:
        NETDEV WATCHDOG: eth0 (cpsw): transmit queue 0 timed out
