Log:
  MFC r227842:
    For IP1001 PHY, do not set multi-port device(MASTER).  Ideally this
    bit should not affect link establishment process of auto-negotiation
    if manual configuration is not used, which is true in auto-negotiation.
    However it seems setting this bit interfere with IP1001 PHY's
    down-shifting feature such that establishing a 10/100Mbps link failed
    when 1000baseT link is not available during auto-negotiation process.
