Adds functions to check for link override firmware support and get the override settings for a port. The previously supported/default link mode was strict mode. In strict mode link is configured based on get PHY capabilities PHY types with media. Lenient mode is now the default link mode. In lenient mode the link is configured based on get PHY capabilities PHY types without media. This allows the user to configure link that the media does not report. Limit the minimum supported link mode to 25G for devices that support 100G, and 1G for devices that support less than 100G. Default override is only supported in lenient mode. If default override is supported and enabled, then default override values are used for configuring speed and FEC. Default override provide persistent link settings in the NVM.
