In the new firmware, MNG veto bit is set by default for new features. It
causes the PHY configuration not to be reset after LAN reset. So PHY power
will be down after stopping device. The internal PHY then cannot be
initialized successfully at device start. Add setting power on for internal
PHY to fix this issue.
